Would You Buy Old Barbecue Sauce?

It's 20 years old and probably isn't any good anymore, but that has not stopped one buyer online that decided that they wanted to buy a bottle of McJordan BBQ Sauce.  The special sauce was used on a limited edition burger at McDonalds called the McJordan, which was around in the early 1990s.

The sauce sold on ebay for just under $10,000 to someone that the seller will only describe as, "someone from Chicago."

Would you buy something like this on the web?  What would you do with it if you did?
