Online auctions are, without doubt, the best places to find shot glasses.  eBay is the 200lb gorilla in this regard and is such an important source of glasses that we've devoted a section of this web site to all matters eBay.   Yahoo.com also runs online auctions but we've yet to see any pre-pro glasses for sale there.  The site is exceptionally frustrating to navigate and anyone with an antiquated modem will spend hours waiting for irrelevant photos to download before they're able to access actual listings.

 

	John Crary maintains a bottle-collecting web site site that often has shot glasses for sale.  Well worth a visit from time to time.
	Sweeney's Emporium is an online antique store that specialises in Western items.  It occasionally carries shots, usually at inflated prices, but worth checking in on from time to time.
