You created a Merchandise feature and you want to adjust the Mininum Shipping/Deliver cost depending on the locations. This article explains how you can achieve that.
It is not possible to set different Minimum Delivery Cost for different locations, as it will take care of all the locations and users' addresses.
As a workaround, you can create multiple Merchandise features in the application, each with different Shipping minimums.
You will have managed to set different minimum shipping/delivery costs for the various locations.
