When the battery on my electric lawnmower from the Home Depot stopped holding a charge a year after I bought it, I expected Home Depot to honor the extended warranty I'd purchased. But the store claimed batteries were not covered because they were expendable.
So I Googled the name of Home Depot's CEO and sent him a polite letter explaining my plight. Six days later, the local Home Depot manager was at my door to replace the battery. When it didn't fit, he gave me a new lawnmower. He even took my old one away!
