Get free stuff with the miracle of complaining!

Write letters or emails to any major corporation which sells products to consumers. Top picks are fast food joints, or prepackaged snack companies like kraft, frito-lay, pepsi, etc. Tell them you're a longtime customer but recently youve bought a product that was spoiled/broken/missing/bad service. For bonus points include a receipt of you buying said product as evidence.  9 out of 10 times they'll send you coupons for free stuff. Take an hour of your time to google the contact info for a dozen companies, and write out one blank letter that you can easily swap one company name/product/reason for complaint for another and start dropping emails. Free stuff will start rolling in!
