Gosh you must all have terribly busy lives 
I couldn't help but click on the link that throwingpebbles (I think it was) posted up - glad I did because it gave me a right laugh!!
I don't mean to flummox your tiny brains, or those of the author over at Timelessvie, but spot the flaw here -
"SOME QUICK MATHS.
Let’s pretend you are a super awesome Consultant and make £536.24.
£600 –
£536.24
= -£63.76
YOU WILL LOSE 63.76 POUNDS A YEAR.
Well, we’re convinced. Sign us up!"
I think this person must be using the term 'maths' very loosely lol. The fact that the person in the example made £536 in commission means they must have sold around £2000 worth of product, so why on earth would they be needing to spend the £600 to remain active?
Dear me.
