No expiry, and one reminder a year that you have it
No expiry
None, ever. Not five years, not ten. The balance sits there until it is spent or you ask us to refund it.
The annual reminder
Once a year we email whoever holds an unspent balance. It is a strange thing to do commercially and it is the right thing.
Refunds
Unspent balances can be refunded to the original purchaser at any time. Most retailers do not allow this and we do.
