If you wanted the game on release day, there generally wasn't a difference in price. Discounting was more rapid on PC games and waiting a month after a game was released could save 50% from MSRP. Some titles would release $5 to $10 cheaper on PC but the big titles would be roughly the same but be discounted much faster than console versions. Prices stay the same longer these days because the PC and Console markets are more even now. Used to be a lot more sales volume on PC games back then.
You also have development cost as well. Used to be that games were designed for PC and then ported to consoles, which cost extra. Now a lot of games are developed for console first and then ported to PC, some horribly, and others good because of good graphics scaling. The process is more streamlined with game elements suitable for both PC and Console graphic capabilities.
