The VFM gift shop does pretty well with T-shirts, ball caps, and low-priced toys aimed at the younger kids, and moderately well with golf/polo shirts. We occasionally sell miscellaneous airplane parts (spark plugs, pistons, gauges, ammo cans, and similar small "man cave decoration" items) as long as the price is LOW. Instruments, for example, sell for $5 to $20. Any more than that and they just sit there. Model kits, display models, artwork, posters, magazines, books, postcards, patches, and pins/jewelry don't sell well at all. Our members bring aviation magazines to the hangar to be shared, and once they've made the rounds, we GIVE them away. There doesn't seem to be much interest in calendars.
Dean has pretty-much nailed it.
I'll add one more "man cave" item that typically sells well: Individual .50 caliber rounds.
One outfit that generates huge activity at Oshkosh each year provides t-shirts via heat transfer. The customer picks out the size, color, and style of the t-shirt. From a catalog he then selects which aviation-related transfer he wants on the shirt. A heat press does the rest. This seems like an excellent way to lower the vendor's overhead as well as providing the customer the ability to "customize" the product. Like I said, this outfit maintains a constant stream of customers to their business during OSH.
