For those of you lucky enough to have a WhSmiths that sells Blu Rays, there are some CRACKING prices. It's a bit hit and miss with pricing and it's worth taking them to the tills. I believe these are nationwide.
Don't bother asking them to price check them because the discount won't come off until the cashier presses the pay button. The titles I had sussed out so far are;
Forgetting Sarah Marshall - £9 HALF PRICE to £4.50
Zodiac - £9 NOW £4.50
Layer Cake - NOW £4.50
Indiana Jones and The Crystal Skull - £9 NOW £4.50 (2 disc blu ray)
plus more... Didn't have the time to get them to the counter but I believe it's all the £9 ones included in the offer.
Found in Salisbury store
will post my receipt for the doubted as
soon as I'm out of the restaurant ( currently being chastised for typing instead of eating!)
Good luck all!
