It could work well for branded and generic foods.
Can of corn, bag of noodles -- things of predictable quality and quantity.
Produce and fresh meat I like to hand select -- most people do?
On the other hand, I have bought some clothing, shoes and other items you would normally hand select from Amazon and have been 80% satisfied with what I received. So, groceries may work so long as the quality control Amazon puts in place is good.
Time is money
