The Post Mark Collectors Club offers many opportunities by which you can enhance your postmark collection. The PMCC Bulletin includes monthly 'Service Offers', through which many members pool their postmark requests to given post offices. Tables of (free!) postmarks are available for the taking at the PMCC Convention and, often, at local PMCC Chapter meetings. For those with specific items in mind, PMCC Auctions provide a great way to flesh out your collection.
The PMCC convention features live and silent auctions at every convention (a tradition begun in 1965!), though we also offer members-only auctions in every issue of the Bulletin. (Unfortunately, we no longer offer postmark auctions online via eBay, which were open to bidding by anybody.) All proceeds benefit the PMCCnotably the Museum.
Indeed, many Bulletin lots stem from the PMCC Museum, although members and other donors also choose to contribute material.
Common auction lots include postmarks (of course), including last-day cancels from discontinued post offices; books, such as old copies of USPS's now-defunct Directory of Post Offices; postmarks from given states sold 'by the pound'; naval ship cancels and cachets; sets of post office linen post cards and photographs; and specialized individual covers.
