How can we use Yahoo to get traffic to our site www.generousgems.com without paying huge advertising fees?

We are an online retailer without a huge advertising budget. Yahoo gets a lot of traffic, how can we get the people visiting yahoo’s main site to find our site… with millions of sites competing for hits how can we get a portion of that traffic? Or how do we get in the “buzz” index or featured somewhere on the front page?
