Can someone tell me the best way of using the Customer Charter Vouchers
(10-15 month) ?

I currently send them to Travelcard-Online in Ireland (With a cheque) for a
Monthly travelcard.

But they have now become Oyster.co.uk, and have said you cannot use charter
vouchers for Oysters.

Does anywhere else except them, where it doesn't take 3 mins for each one to
be processed ?

Regards

Stew
