That's it for me. If the site works good for you then great. It just didn't work for me. First it complained about not being able to verify the address on my Credit Card. Yes, it really is the correct address. The PayPal landing page looks like a purchase page. That isn't such a big deal but it tries to authorize a $1.00 Paypal which I assume is for verification purposes.
Customer support gives you a ticket but then doesn't follow through.
In CardCash defense, when I logged back on it asked if I wanted that I had an uncompleted order and if I wanted to either discard the order or sell it. Like I said before, I have given up on CardCash but at least I know that I can use the Card.
If you are going to use the site to sell gift cards then try selling one for a nominal amount of money before selling a big one. I suspect that the site does work well for some people but if you have problems then you are out of luck getting help based on my experience.
