This is the core problem, right here. At a minimum, people need training to learn what information to ignore so you can navigate the whole thing. Even if you know the store's layout, you still need to have the will to ignore advertising and disregard extraneous information. Being a fast reader that can do fast mental math, also helps tremendously.

Traffic flow is another problem. Wegmans is the chief offender here, IMO, by putting impulse items in massive crates that crowd the store entrance+exit combo. It amazes me that it's not a fire hazard, because it makes entering the store a nightmare. But most grocery stores have awful choke points in produce, dairy, meat, and other high-traffic areas. And of course those are the stores that have no small carts or hand-baskets, obligating customers to gum up the works with big metal baskets that are 70% empty.

A better idea is a store that doesn't flood your eye sockets with information you don't absolutely need. Get rid of the special displays, end-cap bullshit, and vendor promotional stuff. Then, normalize all the price tags and include unit cost per lb/oz/L/whatever to make bargain hunting a snap. Then, measure the fucking carts and make sure that two can get by everywhere in the store. Finally, pick a store layout and stick to it.

I want to say that Aldi is already doing all of the right things, but I could be wrong.

Just try find and track the price per kg of a good, and you are in deep shit. Its some times hidden, after several "get the app", "two for one" just to find out the good is fucking more expensive if you refuse go though the privacy invasing hoops. What the fuck happended to "Limited time offer until this actually cheap batch is sold out!"
