Once a year the PLPG has a show (in St. Louis, other site will considered in for future shows). At the show you can buy and sell lighters, even trade (stories too, not just lighters). Members of the PLPG get a discount on lighters for sale at the show or get your lighters appraised. Entry is free (for members).
Keeper of the Flame Award:
At the St. Louis show a "Keeper of The Flame" is choosen (by past "Keeper's"). The winner gets a plaque and is featured in Flint& Flame. To be considered to the Keeper Award you must make contributions to the hobby of lighter collecting.
I have been wanting to join a lighter collecting club for a while, but I hate that they charge to become a member.
About Flint & Flame:
From PLPG website:
"The PLPG publication is called Flint & Flame. It is 5.5 " x 8.5 " of the most informative documentation on lighter collecting available to the collector today. It is published 4 times per year .
