There's a certain amount of internal competition within the iTunes market that prevents this working across the board. Also, the 99c thing is pretty sacred - if it went up to $2.50 across the board, there would be a huge backlash, which Apple (being teflon coated) would just redirect to the RIAA/record labels - who everyone already 'knows' are evil anyway; ergo (even more) huge PR disaster for the majors.
