Buying Used Books or Catalogues
A great option for stamp collectors and for stamp club owners who would like to enlarge their philatelic library and save money at the same time is to buy used.
If you are a stamp collector that does not require the latest edition of a catalogue or a book a very good option is to buy used. There are many web sites offering to buy and sell used philatelic books and catalogues.
On sites that offer a mechanism for selling and buying used philatelic books it is a very good idea to fill out a "request or offer to buy" indicating the book or catalogue you are looking for and how much you are willing to pay for it.
