The APP refunds

This is just a complaint by me. I'm new on the iPad, but I am not happy about the fact that you can get a refund of the App

Either they should be offer to refund, or need each app manufacturer provide a free demo version of their software to try.

I'm not happy with the last Videohunters app I bought, it has less search functions than even the basic web browser, or at least search functionality I wanted and had no way of knowing until I bought it.
