How much does this cost? We generally have reservations about every day but we've started having to fly in to Tampa instead of MCO because flights from Knoxville are just outrageous and my wife likes to stop and get water and little snacks and things for the room that we can stick in a bag and take with us. We generally stop at a Publix on the way to BLT to get that stuff and this might be handy if it's pretty affordable. I think my wife might usually get about 75-80 bucks worth of stuff. How much do you think it would cost for that? What Publix told me is just that instacart marks up the price of the groceries they are getting you.
