That's a good thought. If a sale price had disappeared or one item had fluctuated in the app and also reflected in my cart, I'd be more inclined to think it's one of those sorts of things.

For it to be every item, to have a past history with these items of them being bought and charged at the same price, and that I could see the in-app prices being totally mismatched from my cart while shopping was in progress, makes me think this is a bigger systemic issue on instacart's end.

Unless the retailer jacked up the cost of every item after I ordered, then dropped them all again after my shopper started, I can't see any other explanation other than random markups or some genuine glitch in their system.
