Not the person you replied to but I don't evaluate app prices in a vacuum. First I think of what paying actually gets me (e.g. no ads), then I consider how it compares to alternatives both free and paid. A paid app has to provide some value over a free app and an expensive app has to provide some value over cheaper apps. Furthermore if an app is priced such that I can buy 3-4 other apps while also being more expensive than any individual apps I've previously purchased then it gives me some pause.
