That's not how the App Store works

The really sad thing is that these are the kinds of issues that Apple could change in about 2 days with a couple of developers. App Stores lack some simple concepts that would go miles toward making developers more money, such as:

- If the app costs more than $0.99, it can be downloaded for the tryout price of $0.99 and returned within 2 days without paying more. If you keep it any longer, you pay full price (e.g. $6.99 or whatever).

- If the app costs $0.99 or less, purchases are final.

- Developers can charge for upgrades from a previous version, not exceeding 25% of the original purchase price.

Maybe there are rules that would be better than these but seriously, why aren't there at least options like these?
