Actually, this happened to me once. I bought a Plus-4 on eBay about 10 years ago. Paid like $10 for it, shipping included, but never got it. I emailed the guy I don't know how many times and eventually got a response back from his ISP that he had passed. (Legit, I checked it out.)
Shyt happens.
LoadWB: Wow, a bit morbid, but yeah, it can happen... (my 8th grade teacher, Mrs. Goodrich, died at school, 2 days before graduation...
