I've inquired about two cues recently. One seller said he'd knock $100 off the price as the cost of shipping to the UK is, apparently, $140. Obviously it's only around $40, so his 'generous offer' was not particularly generous.
The other was asking for $400 on here for a cue - he had the same cue on ebay for that amount, with a 'Make an Offer' amount, so I asked for his best price, with me covering his PP and shipping costs. Well, he knocks off $20, which is roughly the cost of US shipping, which was offered free anyway. He 'forgets' to knock off 10% min for 'Make Offer', the 10% ebay fees & 4% PayPal. His total concession: a calculated zero. Good luck there pal.
My point here is, I HATE it when sellers' assume I don't know the market and don't know the value or costs of things. Anyone taking the piss gets no response from me. I ended up buying a cue from a new seller who didn't bullshit or hard sell - just offered a price that was fair to both of us.
