Few issues:
1. You have a "General Store" category that seems to sell somewhat random items. I don't expect you will sell much of that and I bet its through some sort of affiliate program right? Problem is having a bunch of unrelated crap for sale on the site will hurt your
SEO rankings. If you find you aren't selling much of the non culinary items, dump them. It dilutes your content and context focus and won't help you.
2. If I click checkout and it takes me to amazon for secure checkout, fine... but it's in a new window. Not immediately obvious how to go back to your site. Probably something you can't fix because you can' embed amazon secure in a non-secure page. However ...but I I LEAVE that checkout page, like say I forgot to add something to my cart, and go back to add it, POOF, all the items in my cart dissapear. Now I'm pissed because I have to build the whole order over.
3. Why would I go to you if I can buy this stuff from Amazon? This is a rhetorical question, make sure you have a compelling reason for people to visit you, or they won't.
4. Consider down the road using your own ecom engine. It's easy, free (Except for payment processing) and Amazon won't &*^^%* you on their outrageous fees. 10-12%? REALLY?!
