adidas via eBay offers its adidas Men's X_PLR Shoes in Night Cargo for $39.99. Coupon code "PICKADIDAS" drops it to $29.99. With free shipping, that's the lowest price we could find by $33, although we saw them for a buck less in June. They're available in most sizes from 5 to 14. Deal ends December 1.
The internet has changed how we shop. But for many things, you're still better off buying the old-fashioned way.
