OMAHA, Neb. — Billionaire Warren Buffett is auctioning off an all-you-can-eat tour of the See’s Candy factory in California to benefit an education nonprofit there.

Bidding had already reached $30,000 by Monday, but it remains to be seen whether the final price of this auction will rival the annual auction of lunch with Buffett which routinely tops $1 million.

The online auction that runs through Aug. 13 will benefit Communities In Schools of Los Angeles. It is being offered on the charitybuzz.com website.

Buffett says he’ll teach the auction winner the proper way to eat a bonbon during the half-day tour. Buffett’s Berkshire Hathaway conglomerate has owned See’s Candy since 1972, and he spends hours munching on See’s treats while answering questions at Berkshire’s annual meetings.

For more than a decade, the only time Buffett auctioned off a chance to meet with him was the lunch auction that helps fund the Glide Foundation’s efforts to help the poor and homeless in San Francisco.

The fine print on the candy auction site promises only a meeting with Buffett where the winner can take a picture with the renowned investor and get something autographed, so the candy tour may not offer nearly as much opportunity to learn from Buffett.
