its often easier to send an email asking if the seller will take a tenner less than to work for an hour or so to earn a tenner
most people later reduce their record prices on here if they dont sell if they are willing to take 40 for a record they advertise at 50 one day later why dont they advertise it at 40 to start with ( becasue they know they will get offered 30 ) or because they want to make as much as they can on the selling , either to maximise profit or to reduce loss as they probably paid too much for it to start with.
so by going on what has been said this thread its ok to offer people money at nighters and record fairs but if the same dealer is selling same records by list a few days later then you should pay full price
i know of a very trusted dj on the scene who told me that he had just seen someone pay £1000 + cash for a very rare uk demo at a fair and the dealer then told him that he had another couple of copies at home that he was holding back so to keep the price high
the majority of people selling records on here do it as a hobby etc not a business and i bet that all gains are not reported to the tax man or have vat added to sale prices like the main dealers have to do, then there is paypal / card fees so you can soon add 20% difference to the cost of the record from a cash transaction
if you offer then you take the chance of someone coming in and paying full price against the chance of saving afew pounds
truth is there are alot of dealers selling stuff that is still over priced and alot of wannabe djs willing to pay over the top for sounds and then wanting this money back when trying to sell them on, a couple of things yesterday were posted for 15 and 30 when a dealer i use sells these for 4 and 12 and has them in regulaly
at the end of the day a record is worth what someone is prepared to pay , if they pay your price they get the record if not they wait for another copy to turn up
