I'm praying I'm not double posting, but could see no sign of this deal posted yet! All 6 films so far on Blu Ray, and £40.95 is a pretty damn reasonable price for 6 movies on Blu Ray, especially when they're good ones that all clock in over 2 hours long! The original price seems like a bargain anyway but obviously you can take £3 off that using the Walkabout voucher code and a little more for Quidco.
Get in while the voucher is valid and the price remains!
3% Quidco, presuming Zavvi only pay on what you've paid after discount = £1.14, bringing the potential total to just £35.81 :)
EDIT: 18/9 @ 10am: Price has now been dropped by a pound.
