Used to be a great company. Now they are getting greedy, changed their return policy, and their good customers suffer. Tried to return a pair of boots that were purchased on their old "100% satisfaction guarantee". Now they require proof of purchase where they never did before. This purchase should be covered under the original return policy which I agreed to. As far as I'm concerned this is a breech of contract.
