The very first thing I ever did was SFI back in 1998. I went on to Life Force International (record for reaching crown diamond) and others. Here's a copy of the magazine article I was in in 1998 with SFI. http://ebusinessbonanza.com/sfi/ <<FYI, when you read that - I'm not married any more and have lost some weight ~
SFI paid me for the last 8 years and I don't do much with it. Thats a good thing with an affiliate program as I am more a network marketer and spend my time doing that.
I use and love two of the SFI products. Being vegan I love the natural cleaning products and I use the IAHBE every day. It's where I learned much of what I know.
They have hundred of products though and you choose which gateway page you want to use.
SFI is the only 'Free to join" program I do.
So I wish everyone luck with the restructuring it should be quite lucrative from what I understand.
