If there is something you really fancy contact the seller and ask if they would consider a buy it now and make sure you make it clear that the sale will be through ebay,in 70% of cases they say make me an offer,make a fair offer and you could well end up doing a deal,this only is ok if no one else has bid...
Indeed... and if you're the seller, and have people with a genuine interest coming to view/try something... establish a dialogue, and complete the sale with them - even if it's slightly lower than you might want... it guards against final second sniping by timewasters. From experience, I've suffered an assortment of half baked and just plain horrible/malicious snipe 'buyers' spinning all manner of hogwash...
When folks come to view, agree a reasonable market value... note their eBay user name, wait for their bid to come in, then end the auction early on one (or other) of these 'vetted' bidders. In some cases (in one case, a
second relisting due to timewasters), it's the best way... guards against the same wazzocks bidding again...
