Becoming An Online Dealer

Curious if anyone on here is an online dealer. Thinking about ordering a few PCP / Break Barrel Rifles (at discount) and trying to sell them. Wondering how it's going for anyone that's doing it?

I'd create a YouTube channel, already bought domain name, and have done a lot research on the industry and where we're currently at with the tech in the United States. Can learn the laws as far as which states I'd be able to ship to and what the restrictions are in those states.

This would be a part-time venture, and if need be, one distributor I've talked to is willing to ship out products if I'm able to sell them, so I wouldn't have to cover initial cost of purchasing them.

Thanks in advance.
