What Is it?
It's a script (not WordPress – but more on that later), that makes it super easy to create an Amazon affiliate store.
90 Day cookie (instead of 24 hour)
Great looking Site
Super Easy to Add Products and Categories
You can setup your store, but keep it offline (so when you flip the switch you don't blow your fist impression)
Supports all Amazon websites USA, UK, Germany, France, Spain, Canada, Italy, India, China, Japan and more!
Your products are automatically added (if desired) and updated for you. Your store will run itself
Is it a WordPress Thing?
If you purchase the Fresh Store Builder, you can purchase a WordPress Plugin that allows you to run your store on WordPress (this is great for those who want to have a blog in addition to their store). They have demos of their sites on their website using their script and using WordPress. I will probably be purchasing the WordPress plugin ($37) and moving the site to WordPress (I'm familiar with WordPress).
