Half price sale on all but the most recent (25) and the forthcoming (26) volumes of the award winning comic book series that inspired the hit TV series.

Each volume collects six issues of the comic and runs to approx. 130-140 pages.

I bought the first few volumes on a Humble Bundle a couple of years ago but had baulked at paying £7.99 per volume after that - £3.99 feels a lot more manageable though.

EDIT: Individual issues are down to 69p each too, so only works out at 15p more per six issues if you prefer doing it that way. Normal price is £1.49 so six issues would usually cost nearly a quid more than the respective collected volume.
