I just went into my Blockbuster Account and reactivated my membership for a free month trial with this code: freetrial0618m
With all these free 1 month codes from Blockbuster and Netflix, I can go on for free rental for a long long time. Call it Rental-O-Rama, I guess you can simply keep on switch back and forward with Blockbuster and Netflix with their free 1 month trial. Use different emails and credit card numbers to set up new accounts or get your family members to switch up. Hence forever free rental movies.
I always set a reminder on my cell phone calendar so I won’t forget to cancel my membership.
