I popped into Blockbuster yesterday as I often do to look at ex-rental offers (Captain America Blu-Ray for £8, ta muchly!) and they started asking to review my account details, right down to email address, which obviously I questioned. Apparently, because I haven't used them for a while I'm eligible for their current New Member offer, which is actually pretty good.
14 free rentals for 14 days.
One night only each time, but if you can keep up the pace you can have a different one each night for two full weeks.
I should be able to speed through a chunk of my wishlist and not spend a penny.
