Amuseware has a no refund policy and here's why:
Since all Windows-based games (PC games) can be downloaded and tried out for 3 full days, it is our assumption that you would only purchase the unlock key, if you know you like the game and want to keep it.
Since the CD version of each game is exactly the same as the download version (with the exception of the unlock key, which the CD does not require), it is our assumption that you would try out the download version for 3 days before purchasing it, or the CD version.
All Apple-based tablet and phone games, as well as Android-based games are controlled by the Apple iStore, Amazon, and the Google PlayStore. We have no control over those sales, or refunds.
