Payment failed but coupon still 'used up'

Tried to buy a few games earlier today using the thanks-for-2006 discount coupon. Credit card payment failed; a couple of times were my fault (typo the first time, missing a field that needed re-entering on the retry), but after that I really don't know; it just seemed to have fallen over.

Just tried again a few hours later, and was told that I was entering an "Invalid or Previously Used Coupon/Gift Certificate".

Humph.

Unfortunately, if the Paypal gateway fails to approve the transaction, our system still registers the coupon as used. I've issued you another coupon, which I sent via email.

The same thing happened to me just now - Paypal failed to approve my transaction, and when I went back and tried to use a credit card my discount code was listed as used.

Sorry about that... Just emailed you a new code.
