International Filing, Max Benefits

International Filing can be pretty tricky in the end. Fussing with your MY INFO to get billing and real address agreeing with each other. 
I also found that AFTER paying and before filing Max Benefits wants to see a US address as well.
I think somewhere in the small print Max is only for US residents. Having paid for it, I was unable to cancel it, so I fussed with my address again and was able to file.

Maybe Turbo Tax can do a pop-up window when 'foreign country' is selected as an address to alert people to the billing problems coming up.

I'm wondering who I should comment to, alert, ask about this?
