I think this has a technological solution, but it will be far more complex to solve.
Imagine a virtual store shelf. I for one like to see competing products and prices for those "inner isle items". That could easily be digitized.
Fruit and meat selection is another matter entirely. Short of some sort of remote surrogate system that lets you login and see the shelf at your local market real time, I'm not sure how this could be solved. Sometime I go looking for specific cut of meat and find a better deal on something else. Sometimes I'm curious to see what else is available and/or on sale. I think the capital investment to get something going would be a lot but not insurmountable. You may have to change the way items are displayed, have some high powered cameras to zoom in on meat prices. Fruit, I cant imagine anything short of a robot arm that allows me to login and inspect myself, and even then how do you gauge "softness" without some sort of tactile feedback. Possible but expensive to implement.
