I'm running a commerce shop where we're gonna sell stuff we don't have worldwide rights to.
By using the countries module I've ticked of which countries we can sell each product in by having a countries field on products. (see screenshot below).
I'm thinking it must be possible to make a rule banning to sell a product in a territory that hasn't been ticket of. It should be the billing country of the customer that needs to be validated against what countries the product is sellable in.
Any ideas on how to configure a rule (or another solution) that does this check?
