Basically, you pay a small amount of money to uncover a price of a given item, decreasing it as a byproduct. For instance, if a price is 50 PLN, uncovering a price (which costs 2.50 PLN) decreases it by 1 PLN. The more people uncover the price, the cheaper it gets, until someone actually buys it.
1 PLN is about 0.35 USD, by the way.
Add those three together, and you got a business model that's not worth doing. "Cool" idea but not worth it.
