I've watched some YouTube videos about various arbitrage schemes, including refurbishing. It rarely makes sense at a small scale, but if you can get enough product, you can eliminate the waste by scaling up.
I can watch videos/read blogs about how to duplicate a specific win, but by that point so has everyone else and margins drop.
A few people who find the deal early can make a ton, and they get paid well for knowing what to look for in a good deal. Even then, I'm sure pretty much everyone who does well with this has plenty of stories where they lost big, and they only win on average. It's the same as stock picking; investors don't get paid well to watch their investments tick up, they get paid well for finding the bargains, and sometimes an investment opportunity is too good to be true.
