Tim Cook offers keynote invite, Cupertino lunch in latest Charitybuzz auction

As with past auctions, Cook is offering the winning bidder a lunch with him at Apple's Cupertino headquarters. Added this year however are two VIP passes for an upcoming Apple keynote — typically, access to the company's keynotes is limited to press and Apple staff, and in the case of WWDC, developers.

Charitzbuzz warns that while events will be scheduled at the earliest possible date(s) acceptable to both parties, it may take up to a year. And while the cost of the lunch is covered, the winner is expected to pay for their own travel and accomodation expenses.

The auction begins today and ends at 3:04 p.m. Eastern on May 6. So far 12 bids have already been entered, bringing the price up to $37,500. That's below Charitybuzz's estimated value of $100,000.

If bidding follows past trends however, it will likely exceed that target. Last year's auction took in over $330,000, despite having an identical estimate.

The first keynote available to attend should be on June 8 at WWDC 2015. There the company is expected to reveal iOS 9 and OS X 10.11, as well as an overhauled Apple TV, and possibly new music and TV streaming services.
