Amul - really three pages of being a whinner is enough. We get it, really we do. However you checked the box that said you agreed to the companies policy, even if you did so without reading it, in the US it is still binding you like a contract. Because after all by placing the order and checking the box, you entered into a conractual agreement with Empire Airsoft. As long as both parties hold up their end of the agreement ( you sent money, as long as he dilivers the goods) then neither of you is in violation of the agreement.
The rest of us can not help the fact that you either did not read the policy or that you did not understand the policy. Your only course of action now is to check into international law reguarding this situation but I believe you will find the same thing that I have already stated. As long as the retailer carries out the transaction completing the contract, you don't have a leg to stand on.
On a personal note: I have delt with Empire ( I bought an FN2000 ) and I had a great experience. My friend bought an Echo1 M733 and had a bad experience, but I finally got him to realize that the screw up was not the fault of Empire.
