You can actually pay with cards without creating an account anywhere, which is impossible on most other key-sites. It had all the security checks I know and expect, including an extra phone check, which is a bit slow. First time I entered my phone verification code, it said it was a mismatch (I triple-checked the digits). I just closed the window and clicked verify by phone again and entered the same digits, as it suggested, and it worked :) It also said my order information was incomplete AFTER THE PAYMENT which is a HUGE no-no, but luckily it was as simple as inputting the transaction ID from the e-mail they sent into a small form on their site, which they linked to (read things in red). I felt guided along the way pretty well, but there are a few kinks in the system, though I got out fine, with my game in hand.
