This reminded of an App Store developer I met a few months ago who had an app selling for $10. He was working too much answering too many technical support questions.
What he did was increase the price of the app to $25. Less people purchased his app but his revenue is about the same. The volume of technical support questions dropped significantly because he has less users.
I used to play a MUD called DragonRealms. They charged $10 for a basic account and $30 for premium. The servers were quite crowded and there was a fair bit of lag.
Suddenly they announced a price hike to $15 and $40. Many of the old-timers left. The servers weren't as crowded and laggy.
Everyone called them greedy at the time, but I theorized that they did it because they couldn't scale their servers any more and they had to find a way to earn as much money but have fewer customers. Since they're still in business and haven't lowered their prices yet, I'd say it worked.
