Are you the next Amazon ???
Are you trying to test multiple products to find a winner ?
At the moment your website looks all over the place. So many different types of products. Even Amazon started out as just a online book store. Specializing in books only. I think you need to niche down and maybe only focus on 20-24 products. Quality over quantity. Laser focus over scrambles focus.
Either way you have done pretty good job. Some of your product descriptions are awesome. keep up the good work.
