Consider the possibility that the seller of the Space Shuttle Columbia Mission Patch is exactly what she claims to be. She was deeply moved by the loss, and put up a patch on ebay for $4.95 openers with the proceeds going to charity. If you read the "about me" page, she makes it clear that arrangements will be made for the donation to be sent directly to the designated charity, so the donor can be assured that she does not keep or skim the donation.

For this simple act of charity, she is the butt of jokes and the target of harrassment. If the auction closes at $10 mil plus and the high bidder follows through with the payment, she will be liable for over $15,000 in ebay final value fees.

Just consider the possibility that she thought she was doing a good thing.
