Product Vendor shipping charges
On this plugin it allows for multi vendor purchase, so that a customer can purchase elements from different vendors but you need to Enable per-product shipping method for vendors. That means that if a customer buys 3 x products from me they get charged 3 times the delivery. There needs to be some way to click a box to say if a customer purchases 3 products that are the same they only get charged 1 delivery charge.
That's exactly what I want too.
