In the world of advertising they call what the Coin Vault is using the half "truth technique". It encompasses the use of all positives and no netural or negative comments. The object is to find facts and strech them to to fit the sale. It sound like deceptive marketing but really isn't.
Their prices are high because of the cost of the Television time and marketing costs. Also their profit margins have to be as high as it would be for any other business.
This makes everything seem off the page. It is to us that know the market. But you find this everywhere in advertising. One of the most recent developments is the T.V. ads that off to give you the item free if you pay the shipping. Generally all the company is doing is selling you a second unit at a reduced price. (Probably what it's really worth.)
