Guerrilla Peter Schroeder runs a collection agency near Toronto in Waterloo, Canada. He sends gets postcards to prospects from Florida with the following on the back: "Please don't send my overdue account for collection to Rampart Canada collection agency. I am having to much fun with your money here in Florida!" He adds to the fun by forwarding them to Florida for a more authentic postmark.
Response to his creative campaign is great, but there have been a few complaints. Non-Guerrillas might think even one complaint bad, but when Peter explains that it's just a funny pitch, they sign right up!
