Hard to know Simla. I am sure CulturedCare have some ideas:
1) 1,000 Tweets were sent within the one month time frame they have set
2) Early sales targets are met
3) Their CulturedCare website receives a lot of visitors?
4) There is considerable chatter about their new product out there on the internet)
5) Goodness knows what else!
From a Blis/Frutatrom point of view, at least we know enough ingredient has been sold to make 1,000 packs of gum, and presumably enough product to make the retail launch this month possible.
