I cant believe people are giving you such bad advise...
Your problem is simple, your traffic is low.
I just checked my sources and it seems you get an average of 22 visits per day. Assuming at least half of these are yours, it's obvious you're not getting any sales.
Don't focus on anything related to design, A-B testing, complex in site chat, etc.
Think of it like this, if your shop is located in a hidden alley, and only 10-20 people visit it per day, you can't expect to make any sales, much less get any useful feedback from A-B tests.
There is obviously stuff you must fix, as the images and the logo, but focus on getting customers/sales.
Some good suggestions are:
-Sell through your social circle.
-Get partnerships with blog owners.
-Post about your deals on related forums.
I cant see your site not making sales if you have 1k visitors per day, regardless of all the stuff other users suggested.
