What we offer:

First meeting of each month:   Members and guests may lay out a selection of material "for sale"
Second meeting of month:   An auction of items brought in by members and guests.
Auction:  plus CLUB Lots  ... Around once a month, the Club buys a large lot of stamps, catalog value usually more than $1,000.  This is broken down into small lots and started at 20% of catalog value.  If an item does not sell, it comes back later at 10%. 
CLUB EXCHANGE:  Several large binders full of thousands of stamps.  Take a binder home; take what you need - but put back an equivalent catalog value.  Take $20 worth of stamps/ contribute $20 worth back into the books.
APS circuit books.
Some meetings:  A member gives a short presentation on some philatelic subject.
