A second catalogue and order form can be sent to anyone who buys anything. It is an opportunity to pass the catalogue onto a friend and give that friend an opportunity to join or to donate to the organisation.
The purchaser will benefit from as many ways to pay as possible, such as via crdit card, cheques and postal orders. A credit card hotline can be established, as long as it is properly maintained.
The order form should also give the opportunity to round up the purchase price with a donation.
