I'd still like to see some proof, but I'll accept your correction. Anyway, there are other promotions besides the one you've mentioned. For example, the latest Amazon promotion for the PS3 will surely count for Blu-Ray sales. When I made my original post I was thinking about all of that, not the 5-disc promotion specifically.
Well youd be right about Amazon, its free disc given by amazon, you do not mail away, it is not sitting allocated somehwere, its just a normal movie that amazon is giving you that THEY are paying for to buy form their store so instead of you purchasing it Amazon is, thats hwy its counted as a sale.
And if you want proof you seem able enough to look into it yourself and learn something about the stuff you try debating, and if you dont care enough to know wtf youre talking about dont post, seems simple enough to me.
