i have to wonder if part of the issues w/substituting out pickup items and items being on shelves when you walk in vs. not being in order you've just picked up is directly related TO the stocking of shelves at
walmart. for the past few months the stocking of shelves at the 3 local walmarts has been abysmal. there will be entirely empty within reach shelves while there are products that could back fill up on the top. i can see one of the personal shoppers doing the exact same thing private shoppers are doing and either passing on a product or finding a substitute (and their staffing seems to be greatly reduced as well).
