There have been numerous ones appearing for sale. Admitidly it's impossible to tell if these are extras that have been made available by the club or those put up for exchange.

I heard that Arsenal offer the full value minus a small % to be used as a credit against renewing the follow years season ticket.
I'm sure this would be better received and costs the club no initial cold hard cash.
