Recently the reload bonuses have been around the first week of the month, they used to be near the end of the month. I believe the system is if you play just a few hands at any time of the month outside of playing to earn your bonus, you get included on the email list informing you of the bonus. Its a tough deal to beat, getting 20-25%, but you have to make sure you have the time to play enough hands to get it in 7 days.
