As a website designer I do have some constructive criticism and I hope it is viewed that way and not in a way in which you think I am beating you up
A professional website should look good no matter what computer or device you view it on. Your website is too large for the monitor on my Linux PC (15") and I have to scroll to the right to view all the links.
I think the basic set up of your website has the potential to look really good, but there are many details that have been overlooked and therefore give an overall feeling of sloppy website design.
For instance... On your home page, there are two categories. Electronic Cigarettes, and E-Liquid. The photo for E-liquid looks like someone made a bad mistake and slapped some ......... leaves over a different picture of... a house? Additionally, the text below the Electronic Cigarettes category image is centered, and the text below the E-Liquid category image is aligned to the left. That should be consistent. IE: Both should be aligned to the left, or both should be centered.
The button icons below these two categories are very sloppily placed and they do not look good. The twitter icon is off to the left, and it appears that you have two other buttons plus a link stacked on top of each other to the right. It took me a minute to realize all three of these elements were the same button. You can easily find a facebook logo and link it to your facebook page instead of using what I assume to be a button that facebook generated for you.
And lastly the title of your home page is "WelcomeToTheVaporHouse" or something to that affect. This is a page title, not a text or document file. It can be "Welcome to the Vapor House" instead.
