I know I am new, but I just purchased from them and had a great experience overall. They prepatch and hand-test all cards prior to sale ( everything comes 1.4 ready, was up to me to install AKAIO obviously).
They ship from the Midwest (don't know if I should say more than that publicly?), and FAST. Came priority mail, was told 3 days, but it arrived in 2 (I'm in the Plains)
Prices were reasonable too, considering that it ships from the US, and comes prepatched.
Great customer service too... really fast to respond, and very helpful (I had an issue initially, another person with my name had an order and they sent me their stuff... Same day that I contacted them, they re-shipped, and sent me not only my card, but a prepaid return envelope for the other person's stuff, so it cost me nothing).
I had heard pretty good things about them prior to ordering, and I can say that I was not disappointed by any means. Accidents happen, and they handled it right (and
fast)
