But there is one thing, that pisses me off and that is how to deal with errors in that "buisness"! Meanwhile I bought 8 times samples from 8 different sample providers, which have obvious faulty samples. Some loops are bad sliced or stems are missing, while in the description is written "all stems included" and so on.
Mistakes happen everywhere and that's not the problem! But all 8 providers won't fix that faulty samples and tell me risible excuses like "it's your DAW" or "it's not possible, because the files aren't available anymore" and so on.
So, let's talk about making money. If I find a sample provider, which has really good samples, I often buy its whole offer independently how much it costs, because I'm making music in many genres! If some of that samples are faulty, I write an friendly email and make pictures or send recordings to help to fix them. And if that sample provider fix that faulty samples, I buy again. But from sample providers, which are arrogant and lazy, I don't buy again and I tell all my really many musician friends my bad experience!
I could list that sample providers with easy evidences, but I wrote this only as a warning!
