It is likely that it costs YOU 80 cents to click "Show Price", which also lowers the price by 25 cents. However EVERY person who clicks Show Price is lowering the overall price. So if 1000 people spend 80 cents each to show the price, the price has now dropped 250 bucks.

However that means the site made 800 bucks in 80 cent clicks just to sell this product for 250 less.

so a bunch of people spend money, and one person gets a deal????

Sounds a bit scammish to me. Even if I am wrong, the site seems to have too many hoops to jump through just to buy something...
