We compared prices on popular items from Amazon and Costco — and it's clear which has the best deals (COST, AMZN)

• Costco is known for offering its shoppers great deals on products in bulk.
• However, Amazon offers the convenience of ordering the same products without the hassle that sometimes comes with buying in bulk.
• To see who truly offers the best deals, we analyzed Amazon and Costco prices on 100 items across four areas: household staples, baby and pet, beauty and toiletries, and health — and Costco was the clear winner. 

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 Costco.com.See the rest of the story at Business Insider
