Can't promise the same format, but our 'society' (sounds like a bunch of older women with tea and cookies, doesn't it?) starts out with a silent auction on plants contributed by members for club funds. There is a separate table for "give aways" - often unnamed aloes, agave bulbils, opuntia pads, or other odds and ends. I'm thinking about taking some of my black nursery pots up to see if anyone wants some!
