National Motor Museum Mint Don't buy anything from this company. They charge double of what is advertised. Internet

I ordered the '48 and '56 ford models from National Motor Museum Mint as a X-mas gift. They were advertised as $10.00 dollars for both plus S&H. When I ordered them i received e-mail notification saying I was going to be charged $19.90 for the purchase. I didn't receive them in time to give a s a X-mas gift but recieved an e-mail the second week of January saying that they were just put on order and the charge was going to be $36.90.  Don't buy anything from these scumbags. There stealing everyone's money with this scam.
