I used www.offgamers.com to buy 1 account. They are safe but they are a PAIN IN the ass if you try to buy more then one with a credit card.

They are VERY strict and you have to verify your phone number (a machine will call you and give you a code) then 10 minutes later a real live person will speak to you confirming everything. Once this is finished they will email you a picture of the CD KEY

If you only need one then Its a safe place to go. I'll never use them again though, and here is why:

I typed in the wrong digit for my phone number the first time and my order couldn't go through since the machine couldn't verify my phone number. They had to cancel it (gotta wait 5 days for a re-fund now.)

After this my second order went through ok and I received my CD KEY (they are trustworthy).

Later that night a placed a 3rd order and apparently they have restrictions on how many orders you can make with the same credit card. So they canceled my 3rd order and now I'm waiting for them to refund $17.99 x 2. =(

So again, I only recommend them if your are ONLY buying one.
