First post here, sorry if I screw up. Nike has some men's and women's Metcon 3's at $80 before taxes in select colors.
1. Put the shoe in your cart
2. Use promo code "SAVE20" to get the 20% off (originally 100, then 80 after the promo code).
3. Make sure you're signed up for Nike+ for free shipping
4. Total will be $86.30, your total may vary depending on your tax rate
Additionally, if you have a Discover card, you can get 5% cashback at nike.com. Or you can buy some e-gift cards on a site like cardpool.com at the discount to make the price even cheaper.
