For a different perspective on it.<p>You have a guaranteed monopoly on the price of Bingo Card Creator. I am not sure you would appreciate it if Paypal/(Insert other card processors here) said that they will only let you sell via them if you sold it for 9.99$. I don't that not fair either. You should be free to set the price of your goods, it is not a question of pro-consumer, its a question of using near monopoly to get a power which the market enabler should not have.<p>(Sorry if the last para reads like a personal attack, as it uses a personal example. That is to use an example which you and other hacker news readers are familiar with.)
