Just a heads up, the Bridgend outlet HMV has an offer where there is an additional 20% off everything instore.
Some good offers, as the prices are quite accecptable to start with, worth a trip there for anyone local.
Two deals I noticed were Batman Begins Blu Ray £6.40 (Bought), and PS3 120GB preowned with two games (both rather mediocre) £178.
Apart from that the prices were very comparible with Play or Zavvi, £8
for The American Office Season 3 is another that jumps to mind.
Sorry I can't provide more details, but its just what I can remember
Oh and also its a McArther Glen outlet I believe, so a chance that the offer will be available at other sites
