Cheaper

This is a post everyone should read by Seth Godin:

Here's what I think: Cheaper is the last refuge of the person who's not a very good marketer. Cheaper is easy and cheaper is fast and cheaper is linear and cheaper is easy to do properly, at least at first. But cheaper doesn't spread the word (unless you are much cheaper, but to be much cheaper, you need to be organized from the ground up, like Walmart or JetBlue, to be cheaper). They are, you're not. Cheaper is a short term hit, not a long term advantage. Cheaper doesn't create loyalty, because the other guy can always figure out how to be cheaper still, at least in the short run.
