Play it again Sports has a working business model. So, your idea is sound... you may simply need to tweak it.

They pay cash up front. I don't know if they do consignment. They also offer a combination of new and used products.

I do know that Play it Again, is franchised. So, before trying to reinvent the wheel, you might want to take a look at a proven business model: http://www.playitagainsports.com

Good luck.
