I'm with Ermintrude - put the bread in the freezer. It's not such a temptation there, and will keep for longer.
I did my shop yesterday afternoon and bought a 5 pack of Curly Wurleys. They went straight into the freezer, then last night they come back out to be snapped in half and wrapped in cling film (each individual half) before being put back in the freezer again. Half a frozen curly wurly lasts a good snack time.
It's not mad though, it's called 'taking control'. Much better to repackage into smaller portions than pay through the nose for snack packs and the like. We need to save out cash for fruit and veg (and smaller clothes!!) xx
