adidas via eBay takes an extra 25% off a selection of its adidas men's, women's, and kids' shoes and apparel. (The discount applies in-cart.) Plus, these orders receive free shipping. This is tied with our November mention as the best extra discount we've seen since last June (we usually see 15% to 20% off.) A couple of best bets, with prices after in-cart discount: adidas Women's Tubular Shoes for $28.49 (low by $17) adidas Men's N-5923 Shoes for $29.99 (pictured, low by $20) Note: First-time eBay customers can use coupon code "PERFECT3" to take an extra $3 off. Coupon expires March 28.
