Who is Instacart's target market? Are people really too busy to go to the grocery store and are willing to pay a premium for delivery? Amazon works because their items are actually cheaper than retail. If Amazon items were priced at a premium, few would use it. I personally enjoy grocery shopping. It's a relaxing break from my day. I like picking out my own produce and cuts of meat. I don't think it's something many people would be willing to outsource.
