Free 2 liter bottles of coke! (YMMV)

Thanks to JY for pointing me to this info.

Coke is running an Olympics promotion. Enter codes found on specially marked boxes of coke 12packs, or codes received via daily online request and get a chance to win 5 2-liter cokes.

Each code matches up to some Olympics event. If the US wins that event, you win 5 2-liter cokes.

So one way to get codes is to buy specially marked 12 packs. If you're EC, then that should be easy enough. However, if you're not EC, then just get your free daily ones at:

Request code

You can get up to three a day. One way to do this, after you receive your first code, just go back to the verification page and hit reload. A new verification string should show up, and just go through the process again.

Once you've received your codes via email, go to:
Olympics Coke and enter the codes.

I just started today, and already I've won 5 free 2-liter bottles of coke. Very easy.
