When you purchase Men in Black 1 or Men in Black 2 on Blu-ray, you can get a credit worth $10 — so you can see Men in Black 3! Right now, both movies are marked down to $13 (from $19.99) and qualify for free shipping when you spend $25 or more, or use your Amazon Prime membership.
The way this works is that within 48 hours of your movie being shipped, you will be emailed your promotional code. Within that email will be the link where you will need to go in order to redeem your credit. Once you have done that, you will be able to print your certificate and get a free admission to the movies!
