Ok Mr Charlie big ******** how about if the OP does the deal and it turns out to be a scam will you refund him the money?
** Please fully star out swearing **
I'm not saying do the deal

I'm just pointing out what he is being told on here, by people who don't have clue, is categorically wrong and not to make a decision based off this. If he genuinely feels something is dodgy, i would say go with your gut, but don't make a decision based off jokers screaming SCAM.
Someone posted a screen shot showing bidders bidding activity. Everybody jumped on and claimed that this is the smoking gun. Bidder has bought 3 MacBooks, only scammers do that. Bidder has bought a MacBook and continued bidding on other MacBooks, only scammers do that. When in fact the screen shot did NOT show this, in fact as pointed out by me it showed he had won 1 MacBook and bidded on another 2 earlier or at a similar time. I pointed out this is perfectly normal behavior.
Secondly it was claimed eCheques were some mysterious form of payment, which scammers use to con out their victims. Some dishonest form of payment, when in fact it just a normal and safe way of paying by Paypal. In fact its probably safer as is coming out of a bank account rather than from a credit card.
Now shoe on the other foot, are you going to refund the seller £75 when the genuine buyer, who is well within his rights, tells the seller to do one when he tries to cancel the transaction which he fairly won? Are you going to remove the neg feedback on the seller account, when the buyer, again well within his rights, leaves a negative feedback?
All i have said is for the seller to base his decision off on the facts, and not because of quite frankly laughable claims on here. Ultimately there's £75 at risk and a lost sale, because some guys in GD think the buyers dodgy based off misconceptions they clearly have no clues about.
