Firstly i would like to say this was founded by ALIEN7 im just taking it 1 step further.
ok first what you do is order the recipe book that amazon and helmans are giving away for free. then you enter the code at checkout which is : HELLMANAMZN2
then add anything to your basket and Valah you get free first class postage. all thanks to alien7 for finding the helmans thing in the first place.
