Beta keys are only from preorders directly from Stardock.

Just a note ScriptWolf,

You don't need to keep Impulse up and running while playing. You only needed it to get the game, and keep it updated. After that you can just shut Impulse down until you need to use it again.

That and you would have a copy of the game virtually sitting there waiting for you whenever you needed or wanted it. So that way it doesn't take up space on a desk or shelf.

But it is a simplistic form in action. 

ok stardock i take it back you have managed to create a none resource hogging and bug-filled online store i take my hat of to you i was put off using impulse because of steam which i had very bad experiences with   so yeah i plan to now get the money and preorder it ^^, im just wondering to get the beta i preorder straight off impulse right? (sorry about asking this again i properly already have the answer just want to make sure).

Once it's opened the preorder processing is automatic. You can get the preorder straight off Impulse, or http://www.impulsedriven.com, it's the same store. And yep, it's currently open.
