Loads pretty slow for me I don't like how it is wider than my screen...i have to scroll over to see the left column I am also not a big fan of the levels...meaning I have to click on ebooks...then click on a very small title to see description. Can you make the categories show up with descriptions. And you could use more than one eBook Other than that...look and feel is nice
I would maybe put your navigation above your categories. You most definitely need an image/logo to span the top of your page cause it looks too funky without anything there. Need to tell the viewer what site they stumbled upon. Also, I'm not sure how much work you wanna do, but fixing your post thumbnails to remove all the white around the boxes and just have the package itself being displayed would make it look soooo slick. Other than that...nice page...very clean.
I like php easy to use. You need to add product info on the things you are selling it just loads a picture not any info. Maybe have a little more content to your main page everything seems to be of-set to the left. good start keep plugging away.
