Cheapest BD's in uk???

[NATHAN09]

ive been searching through some online BD suppliers and have found that ASDA (WALMART ) is the cheapest supplier of Blu Ray movies---most movies are between £12.33 and £17.93---ie

MIB ( pre order ) £12.33

I ROBOT (PRE ORDER) £14.93

NARNIA SIGNS UNBREAKABLE ( PRE ORDERS ) £15.43

AVP2 JUMPER ( pre orders) £17.93.

There is a company called THEHUTT which has exactly the same prices as asda---they may be asda trading under a different name for their HI DEF sales ?????????
