Artnet Online Auctions
Artnet recently launched an online art auction (still in beta mode), featuring photography, prints, works on paper, sculpture, and paintings. At a glance there were several hundred works posted, and there's info on the home page for art dealers on how to become an authorized Artnet seller. The site is straightforward and seems to work much like any online auction -- place a bid (U.S. dollars or euros) or just add to your watch list. There are starting bids, estimates, and end times. While the site is just getting started, I bet that with people shopping more and more from home (saving gas), even shopping online for art will become commonplace.
