关于 APP Store 的退款政策

最近一个美区应用退款被拒绝，客服邮件拒绝提供了退款的政策，仔细看了下。

http://www.apple.com/legal/internet-services/itunes/us/terms.html
>Prices for products offered via the Services may change at any time, and the Services do not provide >price protection or refunds in the event of a price reduction or promotional offering.

>If a product becomes unavailable following a transaction but prior to download, your sole remedy is a >refund. If technical problems prevent or unreasonably delay delivery of your product, your exclusive >and sole remedy is either replacement or refund of the price paid, as determined by Apple.


如果买了一个 APP ，发现不喜欢，那么可以退款么？（一般来说前几次退款都没问题，但是貌似 APPLE 对于次数多了之后会拒绝。）按照 APPLE 的政策，其实是不可以退款的。

为什么 APPLE 不提供试用机制？像 Google Play 一样。

很多的讨论在这个网页上都有，就是 Marco Arment 建议的 http://www.imore.com/how-to-get-refund-itunes-app-store
