You are planning to open an internet business selling stock market analysis, and are offering two options to consumers:

A: You charge $150 per year. This grants access to all of your basic financial literacy information, as well as 12 months of access to your stock market analysis memos, which you provide monthly.

B: You charge $50 for access to your basic financial literacy information, then charge $10 each for your monthly stock market analysis memos.

Which one is the best offer?
