Would you buy an extended warranty for a DVD? We can’t imagine that most people would…and if they did, it would last longer than a year. John, however, sent in this receipt from a Texas Walmart store. He writes that the store tried to sneak a $3 “protection” plan along with his ex’s purchase of a $15 DVD. And not just any old warranty: it’s an extended warranty that, as far as we can determine, Walmart doesn’t even sell for DVDs.
