I tried it up and it didn't work for me. Like jakeys I got a response - we were unsuccessful in charging your card and asked for a photocopy of the front and the back of the card. As I'm using VCC-s for most of my payments, it's a dead end.
It is overpriced at regular prices, but you do get both free, once you enter copupon codes.
What seemed really annoying was that they do not register the domain as you enter it, but take their leisurely time. As does the customer service - 6-12 hours per event in both of my cases.
