I think 29% is the best I've seen lulu offer. The coupon code is LEAPYEAR305 but it is only good on Feb 29th.
So head on over to http://www.lulu.com/spotlight/mythmere and grab a couple of copies of whatever catches your eye. I myself recommend a copy of Demonspore and (if you don't already have them) the Swords & Wizardry rules. Demonspore is compatible with all the old school rules out there, of course.
