There are many other ways also of purchasing stamps. Many stamp dealers send out stamps on approval. These are mounted on sheets of paper or in approval books and each stamp is marked with selling price of the dealer so that the collector can make his selection. He returns the others alongwith the money for those which he has kept. Approvals' are d popular way of buying, because the stamps can be examined in the peace of the collector's house.
Many dealers advertise an approval service in stamp magazines.
The collector can ask for an approval of his interest. Another way of buying stamps is through 'New issue' service. In this case the collector makes an arrangement for the dealers to send him all the recent issues of a particular country or a particular theme. Usually a deposit has to be made first. Another way of buying stamps is by ordering specific sets of individual stamps by mail in response to advertisements for sale in stamp magazines.
