Google places value on links according to the weight of the referring domain, in other words how important they consider the website that displays the link.
Google rates websites from 0 to 10 according to popularity and content. A top website like Amazon would have a Page Rank of 10, whereas a new or tiny website with few incoming links would get a zero. So if lots of little 0 rated websites exchange links, guess what Google does? 0 + 0 + 0 +0 = a big fat 0.
What you want to concentrate your efforts on is getting traffic to your site by means of advertising (Google Ads), by selling unique items and by placing relevant content on your site. Build community by adding forums or a blog to your site and get listed by the Open Directory and ZoomInfo.
Visit grader.com and run the free tool to have a clearer idea how your pages might rank in Google, as well as getting some great tips on improving your Page Rank. I've run the tool on your website and came up with a whole list of things that could be easily corrected, like overlong page title, too many keywords, missing image tags, no RSS feed etc.
Work on some SEO and get your ratings up.
Once you can show a page rank of at least 4 or 5, you can then knock on the doors of the big guys and propose a really constructive link exchange. At the moment, you can only attract insignificant links, so don't bother.
Great site by the way, love the look and feel and the products are really nice.
Best of luck.
