A few of the Prima sites will give you FREE money when you download and signup a new account. I know I got $20 free at Royal Vegas when I signed up ... got $10 free at The Gaming Club ... got $10 free at Wild Jack ... and I got $10 free at Trident.
Now I will admit, this was a few months ago ... but they all gave me that money credit and it appeared about a day after I signed up. Didn't even have to ask ... it just showed up. So, check them out.
