Use up the store credit
There's a lot of good information and legitimate criticism of Apple for making this hard/unclear and lacking a support mechanism other than filling out a web form. On the flip side, it's hard to understand how this happens if you didn't sign up for the wrong region intentionally and/or falsify your account details at some point. Also, walking away from less than $1 is hard to complain about - even privately - when you can find some game to zero out your store credit in the majority of the cases.
I'd like some extra eyes and criticism if my closes need to be adjusted and/or some questions really merged to get all the correct answers easily searchable. Since merging questions is something moderators cannot undo, I'd rather be sure we have good chains of close before taking that step.
Once this is sorted, we can enter the remaining questions as canonical ones for the site.
