People always find a way... Never looked at Adobe, but, Cisco, Apple, Microsoft and more all have reseller programs that have agreements that only allow you to purchase from your own country or there are penalties/no rebates/no support/similar if you go outside - along with other rules such as making distributors only sell to partners.

I'm not saying it isn't possible - I buy a lot of kit from mainland Europe where it is cheaper, but, this basically locks me out of the Cisco partner program where I would be a gold partner by now with many other benefits...
