Just received an email from NIKE - Sounds like a great deal
Up to 45% off in the Nike Clearance plus 15% cashback sitewide via Cashrewards. This special offer does not require a coupon code
Free shipping when you spend $100+
Mod Edit: Added "Cashrewards" reference ("cashback" is not always a Cashrewards thing)
Are the prices in American dollars? Seems like the US site.
