Bike Nashbar currently 20% off $100 with coupon code 25DEC [Exp 12/14]. They deal mostly in bicycle components, and bicycling accessories at decent prices. They are currently having an After Christmas Before Christmas sale. Guaranteed shipping if ou order by Friday 3pm.
I haven't spent $100 from them yet. I only purchased a pair of gloves for about $26 and got a 10% off coupon. Still not too bad by any stretch. My next big purchase will be wheels, but I already have them picked out and Nashbar can't help me there.
