Right now Amazon is running a great combo movie promotion, if you’re looking to add to your home collection: Pre-order the Megamind Blu-ray/DVD combo pack for just $20, then pick another qualifying title to buy with it; you can then add a $10 gift card to your cart and it’ll be free at checkout. (Ooooh! How to Train Your Dragon is just $17 in a similar combo pack!)

Don’t forget to select the gift card! It won’t be automatically added for you. Once you’ve got it in your cart along with the two movies, though, $10 will be deducted from your total.

As an aside, I’m loving these Blu-ray/DVD combo packs. Perfect for anyone who hasn’t yet upgraded to Blu-ray (but is thinking about it), or if you have Blu-ray at home but a portable DVD player for the kids.
