The 3rd Pirates film is only £9.99 delivered at Play.com
This is a hot deal as it's a pre-order so the films not even out yet.
Don't forget Quidco. Every little 2% helps.
I forgot to mention it's also the 2-Disk version. I don't think there is even a 1-disk version but a tenner for a new film on 2-disks is very good.
