Apple has come clear on its return policy for the App Store; don"t even think about it. Apple has stated that there will be no returning of an App purchased on the App Store
If you want to try out one of the new navigation programs that can run upwards of $100.00 then you better be willing to part with your money even if you don"t like the program. There is only one way to get a refund but don"t expect or plan on this method to work. "According to paragraph 12B of Apple"s App Store Terms and Conditions, you"re entitled to your money back when, "On occasion, technical problems may delay or prevent delivery of your product." Other than that, you"re out of luck."
The most annoying part about spending a lot of money on an App is that, unlike a retail product that you could resell on eBay, there is no way to recover your investment if you dislike the App.
Apple claims that there is enough information in the App Store to give buyers a good indication of what to expect with the App they are about to purchase. Apple cites that "Customer Ratings and Reviews, App Store Essentials, Staff Favorites, New & Noteworthy section, Top 100 Free Charts, Top 100 Paid Charts, and Top 100 Grossing Charts" provides enough information to inform the consumer about their purchase.
While some companies do offer free "lite" versions of their applications it is not a given for every App. While other stores from Blackberry and Palm do offer the ability to give timed trials of an application, Apple has yet to allow this practice on its own store.
