We've used it to order groceries for our son who lives 1000 miles away from us. He recently had his car stolen, came down with the flu and lives in a very cold area where there is constant snow and ice. We wanted to try and help him out so we started using Instacart to have groceries delivered until he's able to obtain another vehicle. It's worked out perfectly for him. Small charge but it was worth it. Seems like the first one was free. Delivery was within two hours of ordering. I think it's a great service for maybe the elderly or anyone else who isn't capable of getting to the store. After the first delivery we got an email offering, I think it was called Insta Express. Not sure how much it is but it's for a year and you get free delivery. We didn't sign up for that because don't believe he'll need it that long. But they gave us a free trial for two weeks. Leaving the delivery folks a tip is optional and you can do that after delivery.
