A little off topic, but that's reminded me of the time about 15 years ago when I bought an ~$800 GPU for trying out Bitcoin mining. After a month I realised that it was costing me more in electricity than I was making, so I returned it under a change-of-mind policy. I was polite about it, explaining that I understood that there would be a restocking fee. Apparently being polite makes people like you (who knew?) because they accepted the return without the fee.
It's something that ultimately came back to bite me, because the pittance of a coin that I mined back then is worth almost $5000 now. Imagine if I'd kept going!
