Prepaid Credit Card?

[PanicFox]

I'm a future Overgrowth-Buyer
I'm wondering, Can i pay with a 50$ prepaid vanilla mastercard?
Also, is it exactly 29.95 USD, (29.76 CAD) or is there tax with it?
3rd, If i ever accidently delete the game and such, can I redownload it from the site?
Finally, is there a key-registration involved, or how does validation occur?
I hope to be buying the Alpha tomorrow, so I'd like to get these answered ASAP!
Thank you
Panic~

you should be able to, I think it is but I'm not aware of taxing situations in most places, yes, and yes you do have a key for the alpha, it's also highly suggested that you register as a pre-order on the forums so that you can access the secret pre-order forum where you can receive superior tech support and all that stuff.

The validation works more or less like this: You give your key, you get a download link. The actual downloaded game doesn't have DRM or validation mechanics, since Wolfire don't like that. The game will eventually be on Steam, too, and your preorder will carry over into Steam.

The paying process is the same as in the humblebundle store, so when you have bought something from those guys, then you should know the paying process already.
