Brainiac 5 and Spock play 3-D chess sketch cover by Jeffrey Moy

A valid shipping address and default payment method are required to bid.

Slide the bid slider all the way to the right to make a bid at the suggested amount. Sliding will instantly create a bid, and the next bid amount will be based on the current bid and the next increment:

• Below $30: $1
• $30 - $50: $2
• $50 - $99: $3
• $100 - $299: $5
• $300 - $999: $10
• $1000 - $1999: $20
• $2000 or more: $50

You can create a max bid to bid automatically for you up to your max bid.

If a bid is made near the end of an auction, the auction end time will be extended by 30 seconds to prevent sniping.

By sliding to bid, you commit to buy the listing if you are the winning bidder. If you are the winner, we will charge your default payment method 24 hours after the auction ends, or you can complete payment early by visiting the order detail page. If your default payment method fails or you fail to make payment for an auction you've won, your account will be at risk of being frozen.
