Hello, I am working on migrating an existing customer from CSK 2.2 to DC 3.0, and one of the requirements is to have flat rate shipping. I am going to create a new shipping provider so that the customer can set a fixed price for each of his shipment levels, i.e. USPS standard costs $5, USPS International costs $10. I'll update this post with the source and the database changes, once everything is done.
