I would never would order from them , but every month you see more eye candy and more newbees ask "hey I want this plane "
so my advice is really simple if you can not resist losing your hard earned money , use a temporary credit card that is a gift card loaded with the amount that you plan to spend and make sure the card is back by a reliable bank.
So in simple terms , you can go to Walmart , buy a card or two cards $100 each =$200 plust the fee (typically ) 3 to $4 a card , then they can not keep charging your real bank card
