How much does Supernatural Blu-rays cost from Season 1 -->8 & Season 9 (estimate cost) by DIGITAL DOWNLOAD?!

**NOTE: Buying physical blu-rays would cost me an extra 50 $ or more because I'm not living in the U.S.

**What do you think of launching a Kickstarter project or something for fans (like me :D ) who aren't living in the U.S and having problems affording these Supernatural Blu-rays :) to fund one person to buy it and upload it to other (high-end internet connection is needed :P )?
