Shop where you see homeless people!
Want a good deal when you shop? Patronize merchants who have a heart and get better deals. When you are travelling and see a restaurant with big rigs parked outside you can bet you will get a generous portion of good food. When you are shopping and you see a store with homeless people in front of it you can bet that the store is operated by merchants with a heart who will not give you a bad deal.
Encourage others to do so too. Print this little poster on a 4"X6" index card and post on bulletin boards around your town.
