If its the same Ollie, then I know him from the Burner forum....and he's been all good to my knowledge in the past.
But I have to say, if someone see's something they want, and agree to buy, there's no reason why the money can't be Paypal'd within minutes, or a chq/PO arrive within 2/3 days.
Is there any reason these days why anyone wouldn't want to use Paypal if they're legit???
