Tescos are notoriously bad for their display of stock. Like, they don't take any care - if a can or pack of cans gets bent - so what ?
Especially annoying is their propensity to remove all stock off the shelves to feed customers internet orders, so don't expect to find any special offers left when you do your "big shop"!
I was in our local branch on Monday and all computer magazines were there. Donuts ! Pah ! LAck of consideration for their customers. Nuff said !
