I’m not sure if this is region specific but in the Houston, TX area, Blu Ray rentals are FREE for the month of August. You can check out one at a time.
Regular DVD rentals are $2.99/each. They are advertising it as a “cheap” date night. Since my husband and I never go out anyway, it works for us!
If you are not in this area, you may want to call your store first to see if they are participating in this promotion.
