When Shoebuy has a 20% off coupon they are one of the best places to buy shoes. And right now they do (use code SHAPEUP07 - only valid on Athletic Shoes & Apparel), through 1/22. They don't carry Nike but price other brands very well. For example, they have the New Balance 992 running shoes for men or women for $87.56, a new low, after the 20% off code plus free shipping and no sales tax too. This is the only store under $100 (they retail for $130-$140 and are $135 at this New Balance site). Also of note: return shipping is free at Shoebuy so don't worry about sizing, just buy 2.
