Rubber stamps are one of the necessities of a mail order business.
You need to have at least a rubber stamp with your name and address on it, not only for envelopes, but also for commission circulars and ad sheets that you co-publish. If you read ad sheet and mail order publications, you may see dealers selling rubber stamps. There are three ways to sell rubber stamps. The first, and easiest, is to act as a broker for a rubber stamp producer. This is similar to being a printing broker, outlined in an earlier report in this series.
