It's a good service. However, your prices are steep considering other websites offering the same service for cheaper. However, your site has potential and looks a lot more professional than the other competitors.
Once volume picks up I don't see a problem lowering prices. You have to keep in mind a few factors that lead to that price. Taking alt coins is risky as some are more volatile than others. Also, we have to pay a load free on these cards, they cost us more than face value. We have only had the site up for a short time, we wanted to set the prices at a point so we wouldn't risk failure right out of the gate. If the prices were lower and someone bought a $100 card with an alt coin like orbitcoin and the price fell 10%+ before the coins confirmed we would lose money on the sale. The price is what it needs to be right now.
I do not know of another service that sells virtual debit cards for anything but bitcoin. Our site saves people from having to deal with an exchange, you can mine a coin and directly cash it in for a card.
