Today, it is closer to a dollar. You can sell considerably below the regular price and make a nice profit. Other groups that are always looking for ways to make money are Eastern Star chapters, Rebekah Lodges, Scouts, Boy's Clubs, ball teams, Church groups, garden clubs and so forth. These groups can be contacted by mail. Send them a sample of your flyer and a stamp, and explain how others have made money by selling them.
Nothing helps to sell like the word of someone who has tried the plan and been satisfied.
Another method is to advertise your stamps in a national magazine, along with others who are selling the same item. Don't be afraid of the competition. Someone ordering a stamp is as likely to take yours as any other. Before placing an ad, look at a few back issues and see how long the other advertisers have been advertising. If most of them are consistently regular, you can assume that they are making money.
