http://www.Cardavenue.com is another place for selling/swapping GCs.

CardAvenue.com has shut down.  On their registration page, the following message appears: 

 
Dear Cardavenue User:

Cardavenue.com has been affected by the funding limitations occurring in this prolonged recession. It has affected our ability to provide the service our users have come to rely upon. Therefore, we regrettably postponed online operations August 18th, 2009. This will allow management time to find a buyer or seek additional funds. For the safety of our users, all pending transactions, trades and auctions have been suspended. This information cannot be accessed and remains safe. Current members will be able to access MyCA in a limited fashion and you will have limited access to customer service.

We will provide additional information within the next 30 days. Thank you for your past support.

Respectfully,

Jon Vernon
President & Manager
Cardavenue, LLC
