ebay scammers are the worst, they got me once for £14.
appart from that never been ripped off, though I have had one customer not bothering to pay for my services (that's a business problem though I guess and not an online scam)
14 pounds to learn a valuable lesson is not a high price to pay.
Luckily it was not hundreds or thousands because not of the time people get cheated on high ticket items like laptops or electronics.
