For cost reasons, merchants that are not selling to US or Canadian customers will not get a good ROI from my app. Even though I spell it out in the app listing page, I still get international merchants who install the app.
9 times out of 10, they get a bad ROI from my app. Rather than allow them to have a bad experience, is there a way for me to prevent them from installing? Or at least put up a warning in the app install page to get in touch first if they are an international merchant?
