SFI allows us to set up a co-op for S-builder so has to reduce the cost of the S-builder unit. so we can circulate a mail to our down lines about availability and our intention to co-op s-builder units to our affiliates. This is way they can participate in s-builder at a very low cost and also can experience the use and benefit of S-builder so that they can buy it later for their own use and benefit also this helps in duplication.
