i dont personally eat much bread, theres only two of us in my house so we dont get through a great deal,
if we want bread we buy it but it usually goes off faster than we eat it, which doesnt matter as we probably only but a couple of loaves a month
BUT
my parents when i was living at home had a "bread bag" it was a cloth bag with a consealed plastic layer, you put the bread in this and it seemed to last ages??
i dont know where to get them from though, i assume it came from somewhere like a door to door delivered catalogue, the ones that sell this kind of thing? "betterware" is one we get delivered, but may just be a local thing???
