I have spent considerable time working on my shopify store after using Zen Cart and OS Commerce for 15 years. The inabilty to mandate shipping to billing address only is unacceptable. Most companies who deal in high risk items must have this. We sell computers and realted goods. We only ship to billing address. Your software is the only one I have ever seen that does not make this the default. We are getting large orders with mismatching addresses and in every case they are fraudulent. We want to stop this. If we cannot we will have to abandon Shopify.
