Hi Organize1!
Thanks for stopping by the forums and posting here.
Overall, I think you have a really nice looking site. Some things that you are doing well are that you have your toll free number up top-- I think that is fantastic- builds trust. Also, your left nav is all above the fold.
Some suggestions--
I think that if people are spending a lot of time on your site, but aren't buying anything they are perhaps not finding what they are looking for. There are some navigation things you could add, such as dynamic cascading menus (sometimes called fly-out menu) which would get people to the item page quicker-- in less clicks-- basically bypassing a subsection page. Also, I would move up your featured products on your hompage, rather than go into those category images- users can already navigate from the top and from the left, so you can make those call-to-action items more prominent. Also, I'd move HackerSafe down to the footer with your other icons to keep the focus on your mailing list sign-up and your bestsellers- that icon looks a little out of place there.
On your item detail page, which you specifically asked about, I think that the page is set up with best practices in mind. Your add-to-cart is in the right spot- the info table is neatly displayed. One thing to consider is to move your description up and then put those features under the paragraph description. Another way to organize this would be with Tabbed Product Information- you can have the description in the first tab, and then for directions, specs, features or even reviews or an accessory order area in other tabs- our's allows up to five tabs I believe.
Two other features that Solid Cactus developed may help with your conversions are Snap Shop and MiniCart. Are you familliar with these yet? Both are raising conversions, as well as average order size.
Here is a link to the mini-cart webinar--
