Downloading iLife for Mac OSX 10.6.8?

I have a MacBook (late 2006) running OSX 10.6.8. I would like to download iMovie either '09 or '11, but from the Mac App Store, I get a message saying I need OSX 10.7.4. I do not want to pay to update to Lion or Mountain Lion because I am getting a new MBP soon. I also want to DOWNLOAD it, not purchase and old version of iLife on a DVD. Is there any way I can do this?

Thanks,

Adam
