It depends on several factors whether i go back to a store - layout is key: our local Morrisons stack shelves so high it feels like a trek through high rise suburbs, and i don't like the staff much. The co-op is smaller and the folk are friendly, but less choice. So i tend to stick with an online main shop and pick up bits n' bobs from local stores, like our butchers, who stock the only sausages worth a damn for a thousand miles in any direction.
