Tip:

If you haven't, every iOS/OS X developer should sign up as an iTunes affiliate http://www.apple.com/itunes/affiliates/ and use affiliate links. It is more or less transparent unlike other link wrappers. E.g. a link to the same app with my affiliate account will be https://itunes.apple.com/us/app/asteroid-smash/id730150968&a.... (no you don't have to click on it) There's just 2 additional values.

The key thing about this is you can use the campaign tag to track click throughs. It's not about the affiliate revenue.

Wow, this is truly a pro-tip. I had never considered it before. Thanks!

Plus, if someone buys something from iTunes/AppStore shortly after clicking your link, you end up getting 7% commission.
