A good giggle with a $49 price tag.
A lesson learnt that might save one much more monies at a later time.
I was scammed on a non-audio arrangement many many years past, but never forgot the basics of the scam.
Very Recently a knock on the door, was to reveal a up to date version of the scam was in process. The Hawker with dubious intentions got quite the opposite to what they were envisaging as the reception.
Hightailing it out of there would be a good description for how they left.
