There are currently 7 coupon codes that have been reported to be working for FREE Blockbuster Express rentals:
All of these codes expire on June 17th and please keep in mind that they may not work on new releases.
Also, if you rent one new release movie from the normal Blockbuster store for $2.99, they will give you FREE unlimited rentals of movies priced at $1.99 or less through July 4th. There is a limit of 1 rental per day with this promotion.
It looks like Blockbuster is really trying to step it up. I must say that I’m shocked that they are still in business after RedBox really beat them to the punch with $1 rentals from kiosks.
(Thanks Savings and Stewardship!)
