For Mac users out there, check out MacSanta. Twenty-one software companies are having a Christmas Sale. When you use the coupon code MACSANTA, you get 20% off the standard price. The offer is good until 12/25/06. I use FlySketch and VoodooPad. My early holiday gifts look like they will be Fission and PackRat.
NetNewsWire (the best RSS reader for the Mac) is also available for 30% the normal price. Use NGHoliday when you check out and get $10 off.
