Possibly, but the cancellations in my case were not newbies. 
For example, a joblot as a BIn, not cheap by any means. Cancelled hours later as he said he didn’t sell it for enough and I could neg him if I chose too..

The abusive one. The lot came on as starting bid or best offer. I made an offer which was declined. So I decided then to do the auction and won it at half the offer price. Asked why it was cancelled and was on the receiving end of some really nasty abuse…

The suggested selling price when creating a listing is just basically a lie. My selling price is based on what previously sold or currently on sale for.

With so many lens tools out there to identify something and get a realistic price guide to start an auction there would be so fewer cancellations. If the seller can’t be bothered to do any research then it’s on them if granny’s tiara only sells for 99p.

Sadly EBay auctions are now totally unpredictable, not like at least 10-15 years ago when you knew you would get a good price for something and starting at 99p was a normal thing to do
