I'm going to take a quote from lock stock to tell you why whether it's legal or not no one's going to the police
Tom: Listen to this one then; you open a company called the Arse Tickler's Faggot Fan Club. You take an advert in the back page of some gay mag, advertising the latest in arse-intruding dildos, sell it a bit with, er... I dunno, "does what no other dildo can do until now", latest and greatest in sexual technology. Guaranteed results or money back, all that bollocks. These dills cost twenty-five each; a snip for all the pleasure they are going to give the recipients. They send a cheque to the company name, nothing offensive, er, Bobbie's Bits or something, for twenty-five. You put these in the bank for two weeks and let them clear. Now this is the clever bit. Then you send back the cheques for twenty-five pounds from the real company name, Arse Tickler's Faggot Fan Club, saying sorry, we couldn't get the supply from America, they have sold out. Now you see how many of the people cash those cheques; not a single soul, because who wants his bank manager to know he tickles arses when he is not paying in cheques!
Bacon: So how long do you have to wait for a return?
Tom: Probably no more than four weeks.
Bacon: Well what good is that if we need it in six... no, five days?
Tom: Well it was still a good idea.
