I only buy very plain biscuits now (except for special occasions) because I will eat far too many of the nice ones.
The down side is that because I don't eat them too quickly, they are going soft.
I have tried a biscuit tin, and tupperwear, but a week is long enough to make them soggy.
Has anyone managed to find a biscuit container that actually keeps biscuits fresh? About a week to 10 days should do it.
