Amazon charged me £15 for Django blu ray and within the first week it drops to £12.50 ! I've been charged £14 for Bullet To The Head blu ray (Stallone's latest) and it hasn't even dropped through my letterbox yet and it's dropped to £11 !! I called Amazon and they refused to refund the difference. I've noticed this on many titles i've ordered in the past too. Now i know blu rays drop in price after a month or so, but the same week???
My advice is pre-order nothing guys & girls. Simply order them when they're out already as the price won't increase from the pre-order on standard blu ray chart releases.
Bad show Amazon.
