I mean yeah, that sucks, but them refunding you is absolutely the right move. I don't think they did that the last times Amazon removed something from their catalogue.
Edit: I missed this wasn't a refund, just store credit
Still a good move. Its not like amazon is an obscure small store where you wont find anything you actually need or want. You can actually use the store credit
Refunding is like the minimum. Otherwise it is basically theft.
And they didn't even refund in actual money, with which I assume the video was paid with. But instead it is a gift card that can only be used in their store.
The customer was happy with their purchase, so if the seller wanted it back they should bend over backwards to make the customer happy again after taking it.
