When looking to buy something from a user on here.. Don't give them stupid offers if they have already stated a price they want for it and do not ask if they can send the item first before sending payment!.. It will just wind the seller up and they wont want to deal with you lol. If a seller is using paypal there is a slim chance of that seller being a scammer so dont talk to him like you think he is a scammer!.. Just a few little ways buyers piss off the seller to the point where the seller ignores your pms!..
If i want to buy something from someone i just buy it. I dont haggle, dont give a shit about offers, nor about making them. Of course if i was buying a bike from someone who is also into bikes then i might talk to them a bit, but on the day i buy it. My job as the buyer is to buy. Doing anything else is pointless, and a waste of time. So if we ever do business together, i can guarantee i will keep things professional and business like. Having said that, if someone on here is being a cock, you should maybe let the rest of us know so we can avoid them! Also, ive heard of scammers who use paypal. But you can usually gauge if they are one with a single loaded question. Name and shame though, if you are getting crap off someone, then let all the other sellers know, so the person can be avoided. If enough people avoid him, he might change his ways, or he might go annoy people somewhere else. But either way it fixes the problem.
