Yeah, I went to pick up a 'Small Weber charcoal grill' last week and hoped to send it to another member here who was looking for one. By the description and email exchanged it sounded like a Jumbo Joe, 18" across etc.
When I got there I saw a rectangle grill that said (in big letters across the top) Kingsford. I shook my head and almost didn't even go to the door, but 'just in case' I went ahead with it. Sure enough, she walked me over there and said there it is. She called her husband to verify that was the right one, he acted surprised when she told him it wasn't a Weber.
