    Amazon vs. Walmart vs. Jet: Who Is the Cheapest

    Amazon has long wooed customers with an expansive selection, low prices, and free two-day shipping for Prime members. By all accounts it's a winning formula: The site accounted for a staggering 43 percent of U.S. retail sales last year, according to research firm Slice Intelligence. But Walmart is making a major play for a slice of the Amazon pie, introducing free two-day shipping earlier this year on millions of items, no membership necessary. Last year, it paid more than $3 billion for, which launched in 2015 with the express aim of nabbing some of Amazon's staggering revenue. So, where should consumers be spending their e-commerce dollars: Amazon, Walmart, or Jet? compared prices on 75 items across three areas -- household staples, health and beauty, and baby and pet -- to find out. Amazon comes out on top. Amazon was the winner in our price comparison , but not by as much as online shoppers might expect. Here are the highlights: Amazon had the lowest prices overall , beating Walmart and Jet by a little over 5 percent across all three areas. The total tab was $813.39, compared with $859.26 and $859.47, respectively. Amazon had the lowest total by far in health and beauty , $265.59. It beat both Walmart and Jet by about 12 percent. Amazon was also cheapest in baby and pet , at $327.49. But the margins were slimmer: 2.3 percent over Walmart and 4.3 percent over Jet. Jet squeaked out a win in household goods with a total of $219.51. Amazon was right on its heels at $220.31, while Walmart came in at $226.71, 3.3 percent higher than Jet. Amazon had the lowest prices on 14 items. Walmart was cheapest on 12 items, and Jet was lowest on five. Price matching is aggressive , particularly between Amazon and Walmart, which had the same prices on 22 products -- nearly a third of the list. All three retailers had the same price on 15 products. While Amazon's 5 percent price edge may not seem like a huge margin, we looked at products most households will order several times throughout the year, making the savings more compelling. For instance, ordering the same health and beauty products through Amazon three times a year would add up to more than $90 in savings over Walmart and Jet -- not exactly chump change. We didn't account for potential savings with Amazon's Subscribe & Save program, which drops prices anywhere from 5 to 15 percent for buyers willing to commit to a regular shipment. Worth it? Maybe, for products you'll reliably use, but be sure to keep an eye on Amazon's prices -- they fluctuate regularly, and subscribing does not lock them in. offers a simpler shopping experience. Related: 25 Best Finds at Walmart Amazon may have edged out the competition in our price comparison, but there are three big reasons to shop on instead. First, buyers don't need to jump through as many hoops to place an order with free two-day shipping. Second, Walmart has thousands of bricks-and-mortar stores to support its e-commerce business. Finally, prices are still very low. Walmart now offers free two-day shipping on about 2 million items. The only catch is that customers need to spend at least $35. Amazon recently lowered its free-shipping threshold to $25, but that's for standard shipping, which takes five to eight days. For free two-day shipping, you'd have to cough up $99 a year (or $10.99 a month) for a Prime membership. Also, many items we priced on Amazon are available only through Prime Pantry, which means non-Prime members can't buy them at all, and even Prime members have to select at least five pantry items to avoid a $5.99 shipping fee. Other Amazon offerings were "add-on items," which don't require a membership but are available for purchase only if your order totals at least $25. Walmart offers the option of free pickup for many items that don't meet the $35 minimum for free shipping. Although this requires a trip to the store, shoppers can go straight to the pickup desk rather than navigate the aisles and wait in a checkout line. Some orders are available within four hours. Walmart customers can also return online purchases to a nearby store instead of paying for return shipping. Under Amazon's standard return policy, the cost of return shipping is deducted from your refund unless the return results from an Amazon error or the item qualifies for free returns. Walmart and Amazon also aren't as far apart on price as they might appear at first glance. Once we removed four outlier products where one retailer's price was significantly higher or lower than the other two (for instance, Crest 3D White Professional Effects Whitestrips were $41.98 on Amazon versus $54.99 from Jet and $59.82 from Walmart), the gap between Amazon and Walmart narrowed to less than $4 across all three categories. is still worth checking. Although it had the highest prices overall in our analysis, Jet still merits consideration. Without the four outlier products, it was only 3.1 percent more expensive than Amazon and 2.6 percent more than Walmart. It also offers free shipping for orders over $35 (often two-day, although occasionally standard shipping) without requiring any sort of membership. Jet sweetens the pot by dropping prices for customers who are willing to pay with a debit card, forgo free returns, buy in bulk, and buy certain items together. Forgoing free returns and paying with a debit card -- an option on 28 out of the 75 products we compared -- halved Jet's original 5 percent price difference with Amazon. Forgoing free returns might not be a big deal on paper towels, but it would be riskier for purchases such as electronics or small appliances. And some people may not be comfortable using a debit card linked directly to a bank account for an online purchase. If you go through a lot of a particular product, Jet's bulk discounts might be more compelling. For instance, an 81-count container of Tide Pods cost $19.63 in our comparison, but the price would have dropped to $19.20 each for two containers, or $18.67 for three. Jet customers can also stack the quantity discount with the price break for paying with debit and forgoing free returns. That would have made the Tide $19.45 to start and dropped the price to $19.03 each for two containers or $18.50 for three. Again, though, this option isn't always available, and sometimes Jet still can't beat its competitors. For instance, buying five 10-count packs of Ivory soap would have dropped the price from $4.29 to $4.14 each -- but the same item was still only $3.97 at Walmart. Jet also offers harder-to-quantify discounts on items that can be packed and shipped together. For instance, buying Mr. Clean Magic Erasers together with Scotch-Brite sponges drops the price of each item a couple of pennies. The bottom line: One size doesn't fit all. Prices in our analysis were close enough to keep us from making a blanket recommendation, but here are a few takeaways: Shop on Amazon if ... you're already a Prime member. And don't forget that Prime offers additional benefits , including access to Prime Video and Prime Music, unlimited photo storage, and even same-day delivery in some areas. Shop on if ... you're thinking of joining Amazon Prime mainly for the fast shipping. As long as you spend $35 -- not a hard threshold to meet -- you can get free two-day shipping from Walmart without paying for a membership, and prices are neck-and-neck with Amazon. Shop on if ... you don't mind buying in higher quantities, paying with debit, and forgoing free returns. Still, the selection isn't quite as impressive, and some shoppers may prefer a more straightforward shopping experience.

    Amazon vs. Costco: Which One Is Cheaper?

    Conventional retail wisdom states that you'll save big if you buy in bulk. That kind of thinking has made Costco a prominent retail success story even as many brick-and-mortar competitors have faltered in the face of stiff online competition. But is trekking to Costco for mega quantities of paper towels and sandwich bags worth it when you can buy many of the same products on Amazon with the click of a mouse? We at Cheapism have decided to find out just what kind of savings we're talking. We analyzed Amazon and Costco prices on 100 items across four areas: household staples, baby and pet, beauty and toiletries, and health. We did an apples-to-apples comparison, pricing the same product at both retailers. Amazon items had to be shipped and sold by Amazon itself, not a third-party seller, and Costco's prices were obtained in-store, not on The winner: Costco by a landslide If you had any doubts about whether that $60 Costco membership is worth it, let us put them to rest. On most of the products we surveyed, Costco was cheaper -- and many times, way cheaper. Here are our findings in a nutshell: Costco was the better bet almost 80 percent of the time The warehouse club beat Amazon’s per-unit pricing on 79 of the 100 products we researched -- 22 household staples, 18 baby and pet items, 19 beauty and toiletry products, and 20 health items. Amazon undercut Costco only twice on household staples, six times on baby and pet goods, three times in beauty and toiletries, and three times in health, for a total of 14 times. The retailers basically tied seven times. Savings with Costco were greatest in the household staples category That’s where the savings averaged 25.4 percent. Costco was 23.4 percent cheaper on baby and pet items, 21.4 percent cheaper for beauty products and toiletries, and 21.6 percent cheaper for health items. Savings were impressive on several items On three products, Costco was more than 50 percent cheaper than Amazon per unit. That means more than 61 percent savings per tablet on Bayer Aspirin, more than 58 percent per treat on Blue Dog Bakery dog treats, and over 51 percent savings per ounce on Arm & Hammer liquid laundry detergent. On 17 other items, Costco offered savings of at least 30 percent. When Amazon did beat Costco, it was by a slim margin Amazon was cheaper on 14 items, but the average savings were in the single digits -- nearly 6.6 percent savings for Amazon’s winning items compared with 23 percent for Costco’s. The single best deal we saw on Amazon? Savings of 14.36 percent per diaper on Huggies Little Snugglers, size 1, over Costco. The savings are more impressive considering we examined products many households order multiple times a year. For instance, you may buy a 26-ounce four pack of Sensodyne Pronamel Toothpaste for $21.99 that will last an entire year, or a single 8-ounce tube of the same toothpaste on Amazon for $9.84 three times a year. You'll pay almost $30 on Amazon -- and end up with less toothpaste than you would have gotten at Costco. Why Amazon is still a worthy competitor So it's a no-brainer, right? Buy all your goods at Costco and reap long-term savings? The numbers are compelling, but there are still reasons Amazon can make more sense for some shoppers. Time is money Ordering household staples on Amazon is a lot less time-consuming than spending an afternoon in the aisles at Costco. And if you live in a rural area where Costco is hundreds of miles away, Amazon's prices will probably look a lot more reasonable (though as we note in our previous price comparison between Amazon, and , Walmart and Amazon are often neck and neck on prices -- and Walmart offers a simpler online shopping experience that even includes free two-day shipping without a membership). Costco may limit quantities on popular items Costco often prohibits customers from buying more than a couple of items at a time, most often when it puts items on sale. For instance, a $4.40 Costco discount on 30 rolls of Charmin Ultra Soft Toilet Paper resulted in an impressive 41.67 percent savings per square foot over Amazon, but customers are limited to two packs. Quantity limits aren't as common on Amazon. Costco can be an impulse buyer's worst nightmare As the Consumerist notes , the store strategically places "trigger items" -- those are items nearly everyone needs, like cereal or paper towels -- all over the store, making it hard to get the items you need without passing a lot of potential impulse buys. And since the store is constantly cycling in different items, buyers may feel like it's now or never, and end up with a cart full of goods that weren't on their shopping list. In contrast, e-commerce retailers like Amazon still lag when it comes to impulse buying: 68 percent of impulse buys happen in a brick-and-mortar store, like Costco according to a recent survey . Costco's selection is limited Costco is able to offer low prices in part because it keeps its inventory streamlined. The average store offers fewer than 4,000 items to choose from, according to The Motley Fool . If you're looking for paper towels, you'll probably be choosing from one or two big name brands (Bounty, for instance), and Costco's store brand, Kirkland Signature. In contrast, Amazon has nearly 400 million products, according to ScrapeHero , including nearly 61 million in the home and kitchen category alone. As for paper towels, you can choose from Bounty, Viva, Sparkle, Scott, Brawny, Seventh Generation, and dozens of brands you've never heard of. (You can even find Kirkland merchandise on Amazon, though usually at a healthy markup over what you'd pay at Costco.) Moral of the story: If you want variety, Amazon is a much better bet. Buying in bulk may not always make sense Repeat after us: Buying 250 ounces of laundry detergent, no matter how cheap, may not be a good move if you're single and do little laundry, or don't have the room to store a massive bottle. Amazon offers a wider range of quantities on popular items -- in fact, you may be able to buy the same smaller bottle of detergent you'd pick up at your local big-box store using the Amazon Prime Pantry program , which makes it more cost-effective for the site to ship smaller items. The catch? You need to be a Prime member, and you have to select five Pantry items to nab free shipping. The bottom line: shop Costco for savings, use Amazon for a dash of convenience The numbers don't lie: You really can save big with Costco. But buying everything in bulk may not be to every shopper's advantage. That, combined with the convenience and variety Amazon offers, means the online retail giant will probably stay firmly entrenched in any shopper's arsenal.

Amazon items all shipped and sold from Amazon, not third-party sellers. To account for differences in quantities, we calculated per-unit prices and examined the difference between them. All applicable in-store discounts and rebates at Costco were considered, as were online coupons at Amazon. (We did not consider discounts Amazon offers as part of its Subscribe and Save program, as this requires a long-term commitment from the buyer, but we did include items from Prime Pantry, which requires an Amazon Prime membership.) Editor’s note: This item has been updated to correct the data regarding Always Ultra Thin Regular Pads (with wings), which had been previously been listed as cheaper on Amazon. Other figures impacted by this change have been adjusted as well.
