I'm sorry, but I don't use Peapod. I'm old fashioned and prefer to do my shopping myself. I actually enjoy it. It's therapeutic. If you have found a discrepancy I would definitely call the store for a credit to be applied to the method of payment you utilized. I'm sure they will take care of it for you. By the way, my compliments on your checking your receipt. You might be surprised how many times I have found mistakes on my receipts.
Sorry, never used Peapod....I might call and check if it were me.
