I have a small baseball hat collection that's about 75 strong now - whenever I go out of town on vacation or business, I seem to buy a hat either of the city/state, a landmark/tourist sport, or of one of the local sports teams. As you can probably guess, my wife absolutely hates when I bring home new hats.
So in that spirit, I have the following hats earned from points:
PokerStars, Absolute Poker, Party Poker
Working on getting points for a Full Tilt one, and hoping Paradise would open their fukkin' store (that they've promising to do for over a year now) since I really like that site - MORE BONUSES, PLEASE!!!!
Oh yeah, got a snazzy fleece jacket from Stars 2 weeks ago - seeing as I have only 45K in FPPs to use in satellites and shiiiii...stuff, I decided to splurge and spend 1600 FPPs this way. I may get a couple things soon like a mousepad, but nothing major.
