We are purchasing Digishop V10. We will be migrating our Miva Merchant products to the DS cart. Our current cart allows for percentage attribute pricing. Normally in DS you can upcharge the item by a dollar amount if using drop down menu attributes for a product. We need that functionality to happen with a percentage upcharge. DS is written in PHP, so it would involve modifying the php pages to accomplish this task. We are looking for a developer with experience with DigiShop10.
