I went into my local Gamestation the other day and came across the steal of the century:
Face/Off - £3.99
James Bond Casino Royale- £3.99
Both spanking new and both in BLU RAY.
Hurry though, the guy at the shop said that they were phasing these two movies out so they won't be getting anymore in.
Not sure if the deal is nationwide, buy they had other titles in there for cheap - e.g Die Hard 4.0 Blu Ray- £3.99, X-men 2 - £3.99
Hurry before they go.
