Welcome to Webmasterworld :)

Besides paid search (which is definitely worth trying) you can list your products for free on comparison shopping engines like Google Product Search, TheFind, and Bing Shopping.

Google Product Search [google.com...]

Bing Shopping

Check out this link first though:

TheFind
https://merchant.thefind.com/

Hope this helps.
