This is just an American problem because there's no real customer protection.

In Europe (EU) you have at least 14 days to revert any purchase made over "distance" unless the product is either custom made or of such a type that a resale isn't possible (eg. Underwear). You are also allowed to reasonably test the product. The only charges you can incur is the shipping back and if you materially lower the value, an example would be rough handling.

This is the reason for the return policy of 14 days or a couple of hours played steam for example has.
