Canon customer loyalty
The print head in my Canon S900 failed recently. I called the Canon Store to see what I could replace it with in the all in one photo printers. I found one I liked for $199 and said I wanted one. While giving the sales person the information, I happened to mention that my ink cartridges were recently replaced. He said because I currently own a Canon I quailify for the 25% customer loyalty discount and the new price would be $149. Surprised at this sudden deal, I said let me check the internet to see if anyone else can beat that price. I checked and no one else came close.
An added bonus: two day free expedited shipping.
Now that's the way to keep customers.
