Had a table at my club's hamfest last Sunday, shared with several other club members. My part had several small boxes of misc. CD/DVDs (Windows XP/Vista/7/10 OEM installations), misc. computer (video, sound, power, USB, etc) cables, and some adapters (ie VGA to DVI, etc)
Prices were $1 per CD/DVD, $1 per cable, $.50 per adapter.
Ham comes up, asks the prices (yes, they were posted), looking for a power cable. Walks away. Comes back a few minutes later to buy one power cable... for $.50. Told him that the cables were $1, he states "no, you said they were $.50!". Ham at the table next to mine pipes up "No, you were told $1 per cable, and we all heard it!"
Ham finally peels off a $1 from a thick wad of cash, hands it to me, takes the cable, and walks away muttering about how much of a ripoff it was.
Incidentally, I wasn't the only one with power cables for sale. Everyone else's price? $1.
*sigh*
