Where to promote a card website?

(I couldn't find the best place to post this, so here will have to do)

Can anyone recommend a good place to get links to a handmade cards website? In the constant battle to get good a good position in the search engine results, getting good quality links from other sites is vital.

Thanks,

PS: oh, and the links would have to be free or very cheap to get.
