I don't see why anyone would get excited about this promo. To earn 1667 FTPs would mean you've contributed about $200 of rake at full ring tables. So basically you're getting half back, or less if it affects your regular rakeback.
Now that last Take2 bonus was a real sweet deal. Just 1 FTP a day for 25 days. So of $25 in rake, maybe just $4 would have been what you spent to get $50.
Yeah, I got the $100, but won't clear $20 of it at the limits I play, especially if Happy Hour pts don't count. The $10 increments suck as well - 330 pts is no better than 167 pts. And like Debi mentioned, it's hard if you also play at other sites. But I guess if you're playing a lot of medium stakes at FT anyway, and the FTPs just keep coming, it's certainly better than nothing.
