About a week ago I launched my new t-shirt line at www.StripedElephantApparel.com. Since I've been getting plenty of visitors, about 850 unique ones now, but no one has bought anything (other than friends). I know there aren't many designs right now (more are coming soon), but this conversion rate still strikes me as too low.

I'm wondering if there's some usability or design issue I'm missing. Any thoughts or advice would be appreciated.
