Not sure...I do know that when I request a withdrawal from Slotland (or Winaday), I have it WIRED directly to my bank account. I know that Krystallkitty was saying they only send her checks and she was having an issue cashing them at her bank. I don't know if it depends on where you live or what. But Slotland processes withdrawals on Tuesday and it's in my bank on Thursday.
Hope this helps and congrats again!!
