There is a survey for people who have tried products like Keto Chow. If you want to participate you can at http://www.instant.ly/s/d6Eug?source_type=email (and if you don’t, that’s cool too).

At the end of the survey there’s a bunch of coupon codes for Keto Chow along with other powdered foods. If you’re interested, there’s some more info about the survey in the reddit thread about the survey.
