Shoebuy has a 20% off coupon code valid through 10/16. They don't carry Nike but they kill on price for brands like Adidas, Reebok, New Balance, etc. For example, they currently have the best price on the men's New Balance 992 running shoes: just $87.96 after the 20% off code plus free shipping and no sales tax too. They are the only store under $100 or even close (they retail for $130-$140 and are $135 at this New Balance site). The 992 for women at Shoebuy are $94 after the coupon. Also of note: return shipping is free at Shoebuy so don't worry about sizing, just buy 2.
