So far I've spent $40 on the game, bought the first three games for the discount $20, spent about $30 on food and drinks for leveling, $25 on a race change to worgen, and as stupid as this sounds, even after pre-ordering the game and putting the money down for it, I went ahead and bought the digital copy so I don't have to go to the midnight release.
Overall Total: $155 if I did the math right...
How much have you spent?
