I am not joking, but I could come on and say its a brilliant opportunity and should not miss out on it - but you dont know who I am, whether I know what I'm talking about or if I have a vested interest (just this once I'll tell you, I havent a clue!!).
Your best bet is to do some research of the companies listed on the factsheet and make an educated guess as to whether this is a good investment or not.
you shouldn't base an investment decision on whether something is 'fund of the month'. do some research and pick a fund where you understand the investment strategy and are happy with the level of risk & likely returns. this should make you more money over the term of the investment than you will save in comission on the 'special offer'.
