This is my little contribution to the Open Source community after taking so much. It's class that allows you to add ZShop items to your Seller Account on Amazon. When you post an item you will get an exchange id back. You can remove items if you have the exchange Id from Amazon (this is also listed on their website).
There's no guarentees that this will work since Amazon probably changes their layout all the time. But the last I checked it was working as expected for me.
**Please don't email me if it doesn't work, I have enough trouble as it is with school!**
You will need to have the Curl Library installed with PHP.
