The way in which Lime-A-Way changed their website to remove the mention of a money back guarantee leads back to the October 2015 column about written warranties.

A new visitor to their site would not know there had ever been a money back deal. Lime-A-Way gets away with an unfulfilled promise. There are other products that claim to do the same kind of cleaning. You may be just one customer, but patronize one of the other products. Remember that a happy customer tells 3-5 people, and an unhappy one goes on the internet and tells the world.

You'd think that companies would have learned this by now.
