Auction under way for lunch with Buffett

? It’s anyone’s guess how high the bidding will go this year when the chance to have lunch with investor Warren Buffett is put up for sale.

The online bidding begins at $25,000 on Sunday evening. A year ago, two investors paid $650,100 for the chance to have lunch with the chairman and CEO of Berkshire Hathaway Inc.

The auction benefits the Glide Foundation, which provides social services to the poor and homeless in San Francisco.

The auction began at 9 p.m. CDT Sunday and continues until 9 p.m. CDT Friday.

This will be the sixth year Buffett auctions a lunch on eBay and donates the proceeds to Glide. Buffett began auctioning the lunches for the charity off-line in 2000.
