Been having a back and forth for days with #Google Play Store support (yes, actual real human beings, I'm confident of this), over the matter of about 50 cents of Play Store Points.

I may be on the losing end of this one, but I've made some recommendations to help avoid this problem with other users in the future. (Free advice -- which as Allan Sherman once sang, is definitely worth the price.)

It's not the 50 cents, it's the principle of the thing -- there are people who spend a bloody fortune in-app (in my case it was just a simple and relatively inexpensive app purchase) for whom a situation like this could cost them a (relative) fortune in points!
