No spoilers because I haven't seen it yet.
I diverted from m'bike ride to visit a small Sainsbury's where I understood it was £7. At the checkout they tried to charge me fifteen poonds.
Thus after some argy bargy and cancelation it was returne dto the stand. I didn't have my spex and in fact it says £7 *
* when spending £30 or more.
I'm going to download it off Virgin for a fiver.
