The price, at least in the US is as much as they could ask for. If they could get from you $1,000,000 on aspirin they would, trust me. It's called free market. They say that the market will fix any problem. But in reality it's not really free market.

The manufacture price is insignificant but the bulk of the price is pinned on other things like R&D and other costs the pharmaceuticals claim. There are costs but there's also a huuuuuuuge profit to be made.
