this wasnt for a car but a mixer from gum tree. £350 it was which isnt a huge amount of money and a bit of a specialist item, so not many people would know about them.
anyway the ploy is simple : you contact seller. its a woman that is working all hours under the sun and located in a remote part of the country..... but its ok!! she works for a haulage company and can ship you the very heavy item for free. if you are happy with it, you pay her. if not the delivery guy will take the item back!! whats not to like??
well the following bit... you get an email from a haulage company asking when and where you want the item delivering to. once you confirm this info the ask you to purchase a Ukash voucher to verify you have the money for the item. once you have the voucher you simple send them a picture of it, and they send you the item
... only the picture you send them will allow them to see the number on the front of the voucher and cash in the £350
note that this is also done for cheaper and more expensive items where they only want to see a deposit amount for the value of £100 or so. BEWARE - YOU HAVE BEEN WARNED
