Almost every single item gets refunded. I've done three orders now, and despite selecting replacements for EVERYTHING, a third of each order is missing because they can't be bothered to check. And once Instacart gets your money for express membership, if you place even ONE order, you can't get your money back. Please save yourself the misery and just use FreshDirect instead . . . . Update: When you pick replacement items, if you search for a replacement, it deletes all your other replacements!!
