TBH, if I was selling something and someone commented that they could get the item new from a different company my (and your) response would be ‘well you’d be stupid not to buy it new cheaper so why bother posting/emailing this?’
You would wouldn’t you? Otherwise why would you hilight it to the seller? If its an ulterior motive as you know its out of stock or you can’t be assed getting it new then its a cheap-attempt at low-balling.
If I was selling say a frame and someone posted up saying ‘look its the same price here in a UK shop’ I’d pull down the frame and wait abit then readvertise.
Then there is the low-balling with no reason ‘would you sell me the nearly new MINT CNT/carbon bars for £28’?
Thats when it gets insulting.
To be fair Hora if you’re getting insulted about a lowball offer in the classifieds then you’re doing it wrong. People will always try and barter people down a bit on price and as the seller it’s your job to try and haggle back up. The worst you can do is say no, there’s no point in getting offended.
