A couple of bloggers, that I know of, are giving away gaming material for the holidays.
First up is Erik Tenkar at Tenkar's Tavern, doing a "12 Days of Christmas" giveaway.
Second, Douglas Cole at Gaming Ballistic is giving away PDF and print copies of The Lost Halls of Tyr. I was a Kickstarter backer, and I already have the PDF. It's beautiful. It's well written. And there is a chance that you'll get it for free.
Hope that helps some of you guys get free stuff this holiday.
