With 1.3.5-SP4, I want to set up a drop ship supplier. Some products will be shipped by the store owner in New York while others are shipped by this new supplier in California. When a customer purchases products from both, will CS-Cart correctly calculate the shipping from 2 different locations?
Yes it will - it uses the supplier address to calculate shipping.
Will this also work with 2.0?
How about , If I want every supplier have their own pannel where they can add their product and shipping details as individual , how i can able to do this ?
Multi-vendor is in development and planned for release as a separate edition.
