Some time ago I read an interesting article by Robert Woodhead about the principal of allowing people to judge how much they considered a service was worth to them. I read the article at a time when we were wrestling with how much to charge for our online time and task management software, and it semed to make a lot of sense.

We are still wrestling with this problem. Most people consider the idea completely bonkers. Looking around at the many hosted applications currently on the market, particularly the dozens of project management tools suddenly coming online, most of whom charge a tiered fee according to functionality available, you’d be forgiven for agreeing.

We are not convinced that the concept is madness. phentermine lowest prices! Celexa Weight Loss “dangers of phentermine”
