This is a really good service.
You get a free 30 day trial, click cancel membership and get free 90 day membership. If you buy three orders within those 90 days you get a year free! It's a great deal.
I only use the service for dominos pizza and petsmart.com and never had any problems,
No problems with selling.
Iv sold 6 gift cards for $200 since 2011.
Iv never mailed them anything. Always used the sell for amazon gift card.
It says you will receive payment within 24 hours but usually takes 3 days.
Overall it's a great website. Iv gotten paid for random gift cards I don't want to use.
