adidas via eBay takes an extra 20% 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. That's the second best extra discount we've seen from adidas via eBay. (We saw 25% off last week.) A couple of best bets, with prices after in-cart discount: adidas Men's Essentials 3-Stripes Pants for $14.39 (low by $12) adidas Men's Questar Tnd Running Shoes for $36 (pictured, low by $6)
