I just got my copy of The Rock on BD from Amazon and there's a form in it that you can use for any of these three movies. If you already own the DVD version you can send the receipt, etc from the BD you just bought along with the UPC from the DVD and get a $10 rebate. If you paid $19.99 on Amazon like I did, that would make the BD actually have a net cost of $9.99.... more studios should do this!
