"You recently replaced our wood stove with a new Avalon stove. We just wanted you to know how pleased we have been with your stove, and will all of the people you employ. From the original visit to your showroom to the man who did the estimate, to the men who actually installed the stove, everyone was knowledgeable, professional, and great to work with. Thank you for being a business that strives to be above reproach. We have already told others about our positive experience doing business with you."
