This has not prevented stamps from remaining a sought-after commodity, often increasing in value over time.
Philatelists will be able to expand their collections this Sunday as the Dunedin Stamp and Postcard Club presents its latest Stamp Fair.
Chairwoman Val Sparrow said the event would include, in addition to stamps, postcards, DVDs, CDs, books and coins.
People who collect stamps often chose a particular theme for their collections.
Alex Leftwich has a collection of more than 4000 stamps featuring images of birds.
His collection has stamps from all over the world, including lesser-known locations such as the Emirate of Ras Al Khaimah in the Middle East and the Republic of Paraguay.
A tip for budding collectors was to leave stamps on the envelope if they were still attached, because postmarks could also be valuable.

When buying stamps, forgeries of stamps were something to be mindful of.
If a stamp was on offer for a price that seemed too good to be true, that could be a warning sign it was a forgery.
"One of the other ways you can tell too, sometimes, is the perforations of the stamp.
"There could be 14 perforations down that side and say 12 across the bottom or something like that.
"A forgery might not have the exact number."
Another way was to look at the back of the stamp to see if there was a watermark.
"And then you get mistakes on stamps that have been printed ... the colouring is wrong or there has been a word missed out."

Storing stamp albums in a dry, airy room was important. It was a good idea to flick through albums occasionally to air them.
Mrs Sparrow said people coming to the show would be able to buy and sell stamps. They would also have the opportunity to get stamps valued.
She hoped people of all ages would visit the fair and consider joining the 111-year-old club.
"Our aim is to get some young people back into stamp collecting."
