You can opt out of (quit) SFI immediately by going to: https://www.sfimg.com/MyAccount/Remove
Please note that there is NO cost or purchase requirements to remain an SFI affiliate. We encourage all our affiliates to work at their own pace. After all, it's YOUR business. All we ask is that you log in at the Affiliate Center (www.sfimg.com) at least once a year.
If you choose to opt out, we're truly sorry it didn't work out. We try very, very hard to provide the best program we can for all our affiliates because you are our partners. We are successful ONLY if our affiliates are successful. Should you decide to rejoin us sometime in the future, we will be glad to work with you again. Our best to you!
