Don't you just love it when someone offers to pay more than the asking price on Gumtree. I have an item listed on Gumtree at AU$55 and about $11 for postage. Get a text saying he's happy to pay $80 if I post it and he will pay by Paypal or Bank deposit.....Hmmm. Better get my ear muffs out as the alarm bells are starting to ring. 
But being the nice and trusting guy that I am, I send him a text saying it will be less than $80 just need his post code to check postage costs and ask for his telephone number and also if someone will be there to receive it
Get a return text saying happy to pay the $80, giving me a number and just the suburb in Victoria, no other info. So I call the number twice and no answer, fair enough it was a Friday night after all.
Called this morning and funnily enough the number is "incorrect or incomplete". Shock ...Horror, now there is a surprise. So I send a text to him this morning telling him he must have typed in a wrong number and to provide one that works, but so far no answer, I doubt that he will reply.
Bit of a shame really as I would have liked to string him along for quite a while, last scammer that I had, tried to "buy" a large boat fuel tank with some fuel in it off me sight unseen "for her son" and to send it initially via the "Post", also wanted to pay more using Western Union or something like that. Really!! and I thought that I had removed that "S" sticker from my forehead.
I think I strung him/her along for close to a month, traced their details to England and forwarded the details to some law enforcement dept. over there to follow up.
Will wait and see what happens next.
