Which supermarkets sell loose white potatoes (or maris piper, king edward, etc. - just not baking potatoes!)
My local Tesco and Asda only seem to sell loose baking potatoes and new potatoes.
What do you do if you're a small family and can't get through a whole 2kg bag of potatoes? They inevitably get chucked even if I keep them in the dark cupboard to stop them sprouting...
