People are very Naive when it comes to dealing over the internet , especially when a bargain is involved ! There is only really one reason why something is cheap and thats because there is something amiss , people don't sell £10 notes for £8 ! But you would be amazed what people will fall for - For example someone selling 2 Iphone 4's for £250 when they were first out (I used to be a Police Officer) The person conned who had sent money via Western Union ! said that they were going to buy them both and then sell one for £250 themselves to get the money back and by this method get themselves a phone for FREE !
