I don't know how many people are also Contributing Members, but think about it this way:
If SB dropped the price by 50% to $20 they would need to get TWICE AS MANY contributing members in order to make the same amount of money.
That's just not going to happen. Why?
Because whether or not someone contributes is a function of their answer to TWO questions, considered in order:
- Willingness to contribute AT ALL. (Will you contribute, Y or N?)
- Degree of sensitivity to PRICE. (How much will you contribute?)
The vast majority of people who say "I'm not willing to contribute $40" are actually answering "No, I'm not willing to contribute" to the first question. For these people the second question never enters into the decision. If you lower the price to $20 they will still answer NO to the first question, so the price is unimportant.
In my 20 years of marketing experience, I can tell you that most pricing errors are usually of the "failure to charge a HIGH ENOUGH price" variety, with people regularly leaving MILLIONS on the table as they lower their selling price in order chase volume/customers they are never going to get anyway while cutting revenue from customers that were willing to pay the higher price.
Fact of the matter is, Contributing Members are already paying for something they can get for free. Accordingly, price elasticity theory would suggest the best way for SB to increase the revenue generated by Contributing Members would be to RAISE the amount, since those of us that have contributed have already demonstrated that we are willing to contribute and are not really price sensitive.
