why is the new ultra boost so much? im pretty sure that it would do alot but....the super boost (blue bottle) is 90c for one hour but the new ultra boost (purple bottle) is 240c for 1 hour.... the super boost does 20% xp boost for 90c for an hour so should the new ultra boost be 180c (double the price) because the super boost is 20% and the ultra boost is 40%???
