Has anyone ordered entire boxes of used games online?

I've seen youtubers order mystery boxes of hundreds of used games and even consoles in the hopes of making a buck out of all that. So, I was wondering if anyone else has tried such an investment (or a gamble)? Also I was meaning to hire the services of a respected 3PL like this one for the packaging (like this one https://redstagfulfillment.com/) - or am I being too cautious?

Thanks!
