The homepage was fair. The image of the XM Radio image was a little grainy and "Graphical" instead of a photo. A photo would look more credible to me.
I clicked on the "2-Way Radios, Compass, GPS Units" link first, and that page wasn't too hot. No images for the categories? Keep in mind that people are visual, so a picture of each (or icon) next to the link will help people click where they need to go.
If you're really an e-commerce site, why are you using Google ads on your pages? Aren't you selling anything to make money? That's the impression when I see a site that sells stuff and has Google ads on it.
When I got to the 2-way radios, I though I must have clicked on the wrong thing. I saw scanners there. Scanners are 1-way, so that's the wrong category. I had to scroll to see anything 2-way.
I really don't understand why you made 1 link that covers 2-Way Radios, Compasses, and GPS Units. Why not make those 3 links from the homepage instead of having it all under 1 link? It just made for one more unneccessary click in between the homepage and the products.
When I clicked on "Headphones", again I don't get anything visual, just some black links. Why not at least show a couple featured pairs of headphones here? Give me a chance to see that I'm at the page I clicked on. Or, show me the top 10 sellers there and have some links at the top for each of the other categories.
You could probably get a lot of ideas from
my site that you could apply to yours.
If you want some specific examples of what I'd suggest you do to your site, let me know. A mock-up shouldn't take too long.
