I'm not super familiar with ordering from these fellas. Any chance you could post a link to where you can deserve the game?
Go to their Twitter, and they have ordering information there. I haven't ordered in a while, but you normally have to place request by email, and they send you a Paypal link. They where supposed to upgrade their site awhile ago to handle international orders and what not, but I don't know if that ever happened.
They also have an Ebay account, but I don't have access to it currently, so maybe someone can pot it. But on there, you pay more as it's going thru Ebay, and the fees and shipping cost more, which you have to pay. Heavy Arm is a stand up operation, so no worries, but ordering can take a minute, but Steve(I think that's his name) always gets back to you pretty quickly.
