Strangely, Travis boasted 1.9 mil in this interview, but Fontana is saying only "over 1.7 mil." Granted, 1.9 would be over 1.7, but if it were 1.9 they surely would have boasted that as well. I guess they could be counting only the Strange Music sales (Anghellic on), but I doubt that The Calm and The Worst have sold 200,000.
I find it strange too that Travis says they sell the units to retailers at $12, seeing as the stores usually run sales on new releases for $9.99 or lower. That means they would be taking a loss on new releases (when they sell a large percentage). I can't see stores taking a loss like that.
