Update: this is NOT a Buy One Get One Free as I first stated. Sorry for the mistype! The coupon has also expired. Throughout Black Friday weekend, Crocs is having a Buy One Get One 50% Off promotion on men's, women's and kid's Mammoth shoes, including NFL and MLB team styles. Better yet, get free shipping via code CHOOSESHIP. Get the classic Kid's Mammoth for $24.99 and get the Dinsey Hanna Montana Mammoth, regularly $25.99, now $20.99, for half-off. Show your team pride with the Chicago Bears Mammoth for $44.99 and the New England Patriots Mammoth (pictured), regularly $44.99 is half-off. As always, you will pay for the higher priced pair and the second pair of equal or lesser value will be 50% off in your cart. There's no sales tax (except CA, CO).
