This new See's Candy auction could affect bidding on the lunch auction. But then again, the winners of the lunch auction are guaranteed more time to talk with Buffett, which could help keep that event more valuable.
The lunch auction winners get to spend several hours asking Buffett questions about business, philanthropy and life.
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.
Investors all over the world watch what Buffett does and try to copy his moves because of his remarkable track record of success. Through the end of 2012, Buffett's Berkshire has delivered a compounded annual gain of 19.7 percent to investors—more than double the S&P 500's growth rate.

And Buffett, 82, has been gradually giving away his fortune since 2006. He plans to eventually divide most of his shares of Berkshire stock between five charitable foundations, with the largest block going to the Bill & Melinda Gates Foundation.
Buffett's Berkshire owns roughly 80 subsidiaries, including clothing, furniture and jewelry firms. Its insurance, utility and railroad businesses typically account for more than half of the company's net income. It also has major investments in such companies as Coca-Cola and Wells Fargo.
