Congratulations!! it looks great!! I just would do some changes so when you open the website, it's possible to see the tabs with the content. With the text you added, the tabs are too low and not visible unless you scroll down, that is not very convenient.
Another suggestion would be to group a little bit the cathegories. There are too many in my opinion. I would group them in families, so there are only some main cathegories, and under them, the rest..
Congratulations again, you have a lot of listings!!
