Basically, leaving out the people who will buy the Edition, there are three groups.
1. People who will buy the Sports no matter what the SS costs.
2. People who will buy the SS if it's below a certain price level. If it is above that, they will buy the Sport, or nothing at all.
3. People who will buy the SS, no matter what the cost.
The question is, how many people are in group 2, and what are their cutoff price points?
So let's say, out of a 1000 people, a 100 are in group 1, a 100 in group 3, and 800 in group 2. Let's say for all the people in group 2, the cutoff point was $500.
In this scenario, if Apple prices the SS at $600, they sell 900 Sports, and 100 SS.
If they price the SS at $500, they sell 100 Sport, and 900 SS.
Now, let's assume that for every Sport sold, Apple makes $100 profit.
For every SS sold at $500, the profit is $150. When sold at $600, the profit is $250.
So....
(100 Sports x $100 profit) + (900 SS x $150 profit) = $145,000
(900 Sports x $100 profit) + (100 SS x $250 profit) = $115,000
Hmmmmm.... By pricing the SS higher, Apple is leaving some money on the table, but not as much as I thought. Someone please check my math, I'm not too good with numbers.
I suppose you can make up a spreadsheet and plug in the numbers and play around with various percentages and price points and see what happens.
