Fees on eBay are not bad IMO. I mean i sell alot of junk that i will not post on here because it is lower quality. eBay is great for selling worldwide. I send lots of stuff overseas via the Global Shipping program. Oldgas is more north america, but i get the occasional international buyers. eBay gives a product lots of exposer. Might be in your best interest to market your site as much as possible. Word of mouth is great but nothing like a good marketing committee or individual. I did a similar business in college and it did very well. Contact me if you got questions. I like both eBay and other sites to list on. Should be interesting to see the site you have planned.
