Problem.Dispute.Misunderstanding

    A student in my 2002-2003 Contracts class sent me a message describing the following experience:

     "I posted a message on EBay to sell four Paramount's Great America tickets. Here is the exact message I posted:  "You are going to win four Great America tickets good for any day until 2004. No black out dates or times. You will also win four meal vouchers ($10 per voucher) to enjoy a great lunch at the park's restaurant."

     "One person asked by email:  "Are you willing to do a buy now option, if so what would be your price?"

     "I said:  "Sure. The face value of the whole package is ($44+$10) x 4 = $216. But I can give you a 50% off. So $108 it is yours."

     "And he responded: "Great I would like to buy. I can have the money sent thru paypal if you have it set up. I need the tickets by Friday to use on Sat morning. Do you think that will be enough time? As soon as you reply I will have my mother send the money thru her paypal."

     "The outcome is that I did mail him the ticket to an address in Illinois and his mom paid me the money.

     "On the following Monday, I received another email from him. It read: "Hey I got the tickets, but when I called Great America in Gurnee IL, they told me tickets are not valid there. I have 4 tickets I cannot use. Your listing said tickets are valid at any Great America Amusement Park."

     "It turns out we are talking about two different Great Americas. I am talking about Paramount's Great America at Santa Clara. I didn't know that there is a Six-Flags Great America in Illinois. Actually, I did go to Paramount's website to make sure there is only one Paramount theme park called Great America.

    "His thought is completely opposite. He has never heard of Paramount Great America at Santa Clara and he thought he was buying tickets for Six-Flags Great America tickets in Illinois.

     "Now he wants his money back. So what should I do?"

     Is it relevant to your answer that both Six Flags Great America and Paramount's Great America have web sites found easily through a Google search on the words "Great America," and that each web site includes a list of all entertainment parks operated by each?  See Raffles v. Wichelhaus and R.2d Contracts 20.
