Nike is in rare form today, with a discount on full-priced styles instead of clearance. Use the code GIVESPORT at checkout and take $20 off any order of $100 or more (of full-priced items). This includes new releases and seldom-discounted styles.
FYI: It’s $20 no matter how much over $100 your order is, which is a bit of a bummer, but you can still grab an awesome pair of $100+ sneakers for $80.
