Why not ask questions about things related to your website on forums, etc, so it seems like you're not advertising when in reality you are?

That was a joke ;-)

First of all, nice site. Not sure what market you're aiming for but I for one would love to see the death of ebay. How did you get those products on there? Are they yours? Friends?

Consider putting your site on here: http://www.betabait.com/

Maybe you could get in touch with a few local charity shops (or any shop really) and ask them if you could photograph their products and put them on your site? That's how Zappos got started :-)
