Sign up at FullTilt with rakeback. Deposit $600 and get $600 bonus. Clearing the bonus will require you to get 10,000 points which is equivalent to $1000 in MGR for you.

At 27% rakeback this will result in an extra $108. Play breakeven poker and you've turned your $600 into $1308.

Or you could go to something like pokersourceonline and do all their promos and get a bunch of points and order stuff.
