This deal has ended.
Dick's Sporting Goods now has 47 different Crocs sandals for $29.99 plus free shipping but if you pay spend $0.01 more (here are some cheap examples) and pay via Google Checkout you'll get a $10 off $30 discount, cutting the Crocs to $19.99 shipped, effectively, the best deal on the cult-hit shoe along the lines of UGGs - a little ugly but very comfortable. They are made with a special resin that is lightweight, super comfortable and molds to your feet. Kids Crocs are $5 less. Plus, there is no sales tax (except CA, GA, KY, MA, PA).
