If you buy a credit card from this person you might as well just go donate your coins to a random address, he is a scammer and he will not give you anything and the site is not functional.
BECARFUL DO NOT BUY I WAS SCAMMED BY HIM
There are virtually no anonymous bitcoin debit cards right now, so when you see these kind of sites offering you anonymous, prepaid solutions, you should be extremely wary. Most of them will get your money, and run with it.
Also, I took a glance at their rates, and it's just horrendous. Almost 20% markup even on the best priced cards, definitely not worth it. You can get much better rates on localbitcoins, selling for bank transfer.
This is why research should be always done on any purchase from a site that online, that you haven't used before. You can't trust a stranger to deliver on their promises all the time.
