I got my vaporbrothers from Vapor Warehouse and had no problems. What do you mean you got two bills? Are you looking at your bank account online and you see two transactions? If so, this is pretty common and nothing to worry about. A lot of times a merchant will get automatically get approval from your bank before accepting an order. Your bank will initially show this as a transaction. Later, when your order is actually processed the merchant will do the actual charge to your account. Now your account will show two transactions. Fortunately your bank won't automatically send the money out. It is actually pending until they receive the final request from the merchants bank. There will be only one final request from the merchants bank and after a few days your bank will erase the inital transaction from your account since no request for those funds has been made.

Hope this helps more than confuses.
