Hi,
Unfortunately, this might not be possible at the moment with our plugin. We might look into adding this feature later on. The issue is, if the user does not input their shipping zone/ address, it is not possible to check which zone they are from. However, for now, there is a workaround.
In the plugin’s settings can you please try and enable: Messages > Display on empty cart.
Then in Messages > Product page > Product page notices > Enable
In the Message, you can say something like: “Minimum order requirements are set per area. Please login or register to access accurate figures. You must have an order with a minimum of %amount% to place your order, your current order total is %total%.”
