what kinds of "VIP" offers have you gotten?

on a few of the rakeback sites, i have seen that sites offer higher rakeback to people who pay more than 4,000 a month in rake. have any of you been a part of these offers? if so, how much have you received? you don't need to tell me the specific place, i would just like to know what my options are, as i am currently looking for a few new sites to begin playing on

If you are regularly getting 25% back.. 4-5K MGR should bump you up to 28%.
