Hi! I'd be interested in that, too. I have not yet sent the coin-vouchers to MB, but I am about to. I'll probably get around to stop by the post office on Monday. I'd have sent them in long ago, but the vouchers say that I'm supposed to send the bills along, and I had to go back to the store to ask for a bill, since originally they didn't give me any. All I got was a simple bill with the prices and the name of the store on it, I dare to hope that's enough...
When did you send in yours?
