New MBP question about up-to-date program

Bought a new MacBook Pro two days ago (July 22nd). I'd like to leave it at 10.6.8 for now. But I only have 30 days to redeem my "free Lion upgrade" from Apple as per this: http://www.apple.com/macosx/uptodate/

Is it possible to redeem this offer without actually downloading/installing Lion right now, and then install Lion in the future?

Also, can I download Lion without installing it, or will it automatically install if I download it?

 

OK, I've gone through the process on the Apple website of ordering Lion for free and getting the redeem code (AKA "Mac OS X Lion Content Code") on my receipt. I don't want to download it now. If I redeem this in the Mac App Store, will it automatically start downloading or will it just be an item in the "Purchased" list available to download?

EDIT: Well I redeemed the code and it started downloading. Oh well, I hope it doesn't take too long or require I install it.

EDIT 2: I cancelled the download, and it now appears as available to install in the Purchases. I guess that is the process you must go through if you want to do what I wanted.
