Short answer: offer an additional pricing choice. Even a stupid one.
Longer answer: Check out this video. It's almost perfect. It shows how adding a single pricing choice can add 43% to total sales revenue. It's presented by Professor Dan Ariely, a delightful MIT economist. And it's only 114 seconds long.
Why don't you take the 114 seconds to watch it? I'll wait ...
Here's the math on the different options:
With two choices:
68 x $59 = $4,012
32 x $125 = $4,000
Total: $8,012
With three choices, one of which is stupid:
16 x $59 = $ 944
84 x $125 = $10,500
Total: $11,444 (an increase of 43%)
OK. Interesting, huh? Ariely's main point is that customers often aren't very good at knowing their own preferences, and they take cues from outside indicators of value, such as pricing options. By offering a third choice, even a ridiculous one, customers end up perceiving more value in the more-expensive choice. That's why Wendy's sells a triple cheeseburger — not to sell lots of triple cheeseburgers (they don't), but to sell more double cheeseburgers.
The moral of the story is not to offer ridiculous choices; it's to offer choices that lead your customers to find differing amounts of value in the various options — something you can't do if you bill by the hour.
The rest of Ariely's TEDtalk lecture is here. It's great, and it's only 17 minutes long. His book, Predictably Irrational, is here. I confess that I haven't read it yet, but it's definitely on my list.
Big thanks to Ed Kless who highlighted the video last December.
[Update 9/11/10: Ed points out in the comments below the effect this has on profits, given that The Economist's costs don't change. Very cool, Ed.]
