Overall, I like the theme. Very clean and easy to read. A few suggestions.
1) The hover states in the secondary menus are hard to see so I don’t really know what I am clicking on.
2) I would fix the item listings so that “Add To Cart” is always aligned with the next “Add To Card” button. Maybe add some space between the item name and the button. If the name is too long, you could always use ellipses. Or change the font size. Or implement a character limit. Currently, it is the only part of the site that looks messy.
3) Eliminate the box shadow on the menu (looks kind of outdated) and ease up on the box shadow and change the color of the search bar, as it looks out of place with the rest of the theme.
