A WAY TO OFFER MY CUSTOMERS CASH BACK ON ORDERS - PRICE IS NEGOTIABLE i DONT KNOW WHAT IS REQUIRED? - THE SAME AS [login to view URL] I THINK I NEED 2 THINGS 1. a browser add in or add on. that you can choose to activate. 2. And some sort of code or programme that I imagine is installed on the particular ecommerce site participating in the system!?? Then when a purchaser goes to a participating ecommerce websites you see this green strip (jolleywallet) and it offers example a % of the total amount you spend "cash back" in your PayPal account. (the amount advertised) on the website ranging from 3% - 20% (whatever) is agreed by the ecommerce site & (jolleywallet). To claim the cash back all you need to do is simply first register with (jolleywallet). Then you choose the offer of example 3% cash back and complete the purchase on the ecommerce store. Then within some time the example 3% is paid into your PayPal account! I have 2 sites selling products I wanted to offer this system on my website. I contacted jolleywallet many times (all they give you is how to register with them as a purchaser. I have tried many times to get this system on my ecommerce sites but they are either too busy, my site too small, or they are not offering this product/ system to particular countries. They will not even give me any information? PRICE IS NEGOTIABLE i DONT KNOW WHAT IS REQUIRED
