I remember my first time extrapolating. Got Woolworths to trial a line I was selling in one store. They made the mistake of telling me which store. Cue a 7 hour round trip to said store to buy all the stock and then when the sales data came through, an email to the buyer telling them if they extrapolated those sales to all Woolworths stores they’d sell 300k pieces a year so should place some bloody orders quick!
