aHA! I found something useful to comment on: typography. Something was bugging me about these buttons, the were too... too much something. Perhaps a slight bit too large. Then I noticed that the lettering was nice and modern on them, and does not look like your category headings ("Categories", "Best Selling", "Shopping Cart", etc.). Looking closer, I see two (or three?) sans-serif fonts in use, creating what has been called a "conflict of similarity." In short, making all the fonts match *exactly* will make for a more polished presentation.
On the product page, you use this nice touch to make your photos look more "finished". But you do not use the same touch on the photos in "best selling", nor the ones on the Home page. This looks, to me, like an opportunity to give your work a little more polish.
I see what you're doing with the category headings and the border space to set the sub-area apart, but...
I see a slight rounding or bevel in the heading-background graphic, but none in the box. It's creating a slight impression of mis-alignment. It might be fixed by using a comparable amount of corner-rounding on these white boxes. See my next note.
Like here, the bottom-buttons have a rounding on them, and it lends a nice "finished" appearance that makes it look more in harmony with the "Best Selling" category heading. Perhaps if the top corners were subtly rounded too?
These buttons are hard to scan being that they are the same color as the rest of the content. For ease of use I would make the background a slightly darker grey (#efefef) just to allow it to separate from the content above it.
Have you thought of what happens with longer titles? Does your text wrap? I would recommend pulling the boxes out of the container or replacing them with left right arrows and having 5 smaller boxes show there current position in the slider.
What if you took this content and placed it to the left under the photos. This would allow you more room and separates the static information (table) from the main content (description) in a condensed area and brings the important description Higher on the page.
