We've got a client that wants to offer free shipping based on certain conditions; namely, whether the order > a certain dollar amount. If the condition matches, then they can get the cheapest free shipping, but only to a particular region, namely USA, and standard mail.
I can't see how to do that in the promo system. I can match a promo by total $$ amount. I can't then give free shipping(ProductPromoWorker references PROMO_FREE_SHIPPING, but that isn't in the seed data). Even fixing that problem, I don't see a way to change the list of available shipping methods for a product store. Can anyone offer any pointers?
