On Gumtree, ad posted 2hrs ago, Ken from Langdon Hills, Essex, posting for 5 months, asks £500 for this:
Unwanted gift. Brand new. Comes with case, reeds and cleaning cloths. Collection only from Basildon. Dark grey colour with gold engraving. SOLD
Some poor sucker has thought "My god! A Yany for £500!" and lapped it up.

No, you really don't have to list them, there are SO many. But for the unaware, £500 goes down the pan.
"Unwanted gift" my backside. I have reported the ad to Gumtree and suggested they not only remove it (too late) but also remove the advertiser.
