I love bonus whoring. Rude- if you already have an account at these places, call them or email them and you never know what they might say. If you get someone on the phone who is in a good mood or trying to make a sale, they may give you the same offers as a new account.
Some others that I always hit right away with new friends that I get in to bonus whoring are Bodog, Carib, and Nine. All three are decent outs in addition to having great bonuses. Bodog has 40% referral and 10% sign up, but they cap when you deposit 500, carib will give you 50% that expires upon cashout, but you can just bet the whole account vs. Pinny for a hedge and guarantee yourself 25%. Nine will give 99 for 99 match on the first 99 that you deposit, and 20% after that, plus a 20% referral. You have to call nine to get that one. If anyone on here doesn't know someone with these accounts and wants to put me down as a referral, I will gladly hit you back up in the future for sure. I still need to get involved with mansion, cascade, trojan, and many others, so I will hit you guys up for sure. Just let me know.
