I see, my bad. Still, why even walk around empty aisles full of food pictures then?

It seems like a strange UI for something that could just happen in the app before you even get to the store. Seems like a waste of space too since everything will be itemized and stored in the back on shelves as well.

I understand that user behavior doesn't turn on a dime but Amazon customers are already used to ordering online.

I'm saying have items for display to allow for browsing. You don't need shelf space for 24 boxes of cereal - you keep them upstairs. The aisles can be narrower(no carts, shallower shelves) and you still have the experience of browsing and getting people to make impulse decisions. It's like a hybrid between browsing Amazon and being in a real store.
