It stands to reason that if you buy in bulk it shpuld be a little cheaper yes? Well... If you buy a 1000 booster for a month, that is $100. And with a 1000 booster you gain 20 times the amount of a 50 booster, right? So that means that 50 booster for 20months = 1000 booster for 1month. So why is it that a 50 booster for 20 months costs (if buying in leaps of 3 months) only $87, while a 1000 booster for 1month is $100? Surely a 1000 booster should cost at most $87? Not that im complaining, or that anyone really cares, but it makes sense.
