The most surprising thing for me in switching to a 30 day refund policy was several of the people who asked for refunds either made another purchase later on, or referred someone else to me for a sale. I hadn't expected that. It's not the norm, but I can think of at least five instances in the last several months where that happened. No company likes giving refunds, but if you treat customers well, even when something's not right for them, you may be able to earn their business for the next time around.
