I don't know if anyone will find this interesting but I ran the math on Paizo's new mini's line known as "Pathfinder Battles". The Standard Boosters contain 1 Medium and 2 Small miniatures and is $3.99 (all numbers are without tax or shipping added). The Large booster has 1 large mini for $5.99. The "Brick" contains 16 Standard Boosters and 3 Large Boosters and cost $74.99.
Like you, I'm assuming we'd save money buying the brick which has 16 S. boosters and 3 L. boosters (bulk discount or something). They also sell "The Case" which has 64 S. boosters and 12 L. boosters and cost $274.99.
The Brick
well... 16 x $3.99 = $63.84, 3 x $5.99 = $17.97. $63.84+$17.97 = $81.81.
the cost of the brick is 74.99, so the money saved for buying the brick would be $81.81-$74.99 = $6.82. that means you roughly get 2 extra S. boosters. (total:2 medium mini's and 4 small mini's).
The Case
well... 64 x $3.99 = $255.36, 12 x $5.99 = $71.88. $255.36+$71.88 = $327.24.
the cost of the case is $274.99, so the money saved for buying the case would be $327.24-$274.99 = $52.25. that means you roughly get 8 extra S. boosters (total:8 medium mini's and 16 small mini's) and also an extra 4 L. boosters (total:4 large mini's).
in summation
You save $6.82 for buying the brick compared to buying the boosters individually.
You save $52.25 for buying the case compared to buying the boosters individually.
