Bones

Well, I've had this happen before and I know many others have, but, here is what it is:

A bank for bones. Like say you had to hold bones for something but then you or someone else goes on your account and spends all your bones etc. E.g: Mad at you like a sister and goes on your ala and buys something or you buy something by impulse and the user got frozen etc.

OR if you were saving for a custom or just want to keep them in a safe place. I know I've wanted a bone bank before so why not anyone else?
