Abusive is a perfect description. Exploitative too. I’ve always viewed store credit as a sucky refund policy. Offline. Whenever I discovered these, usually because I needed to return something, these shops lost my business.

And the above is not even the same situation when you really look at it. This person didn’t want to return something. They made a purchase they wanted to keep. Then Amazon just said, “oh, we’re repossessing that media and keeping your money. Feel free to use this store credit on something else for which we can repeat this scenario all over again at will. Have a great day!”
