Block And Strap
Customers are given option to buy items on Amazon through this app?!?! Why would I install an app that sends to traffic to another store!??!
there is nothing instant about it for the customer in your shop.
when your customer clicks "add to wishlist" they are directed away from your shop and asked to fill out some form. NOT COOL.
it should keep them on the same page, and just have a quick and small pop-up that asks for their email to track the list with a pre-checked box that agrees to share on their facebook page .
