I don't know if this has been posted before, but I was at my Walmart today and got the DOTM (BD + DVD + DC) Combo-Pack. The sticker price still said $24.96, but when it ranged up on the register I was shocked to see it at $14.96 on the receipt!! Thought that I'd spread the word.
I really doubt it would have dropped. You may have seen the screen on an angle, because it hasn't been out for long enough to get a price drop, nor would the drop be $10, as its new. Used, maybe, but not new.
