I think part of it is also availability. We know, as consumers, the average price of certain goods, and in an effort to save money, avoid spending when it seems obscene, without looking at the bigger picture. If the average price of mobile apps was 40$, and your equivalent app was sold by 20$, it would sell like hotcakes.

In comparison I can buy t-shirts for 5$ so I would never pay 25 for one.
