You are confusing confidence intervals (used to say that you are confident the increase is positive at all) with error margin (the false precision in the 3rd significant figure).

You are right, my bad! Thanks for catching that in the comment above, I've updated it
That does not bode well for the rest of the methodology...

Mixing up terms in casual conversation happens to everyone, and is not a sign of a meaningful problem.

I don't know why people downvote you:
//> we finally have an absolute number of sales measured, but no way of knowing - representing all sales within a period or just cherry picked?
//> for the rest of the population, did it reduced sales?
//> was there any randomised test or not, because in the latter case there could be other biases we're unaware of
//> the increase is compared to what exactly?
//> any WHY is purely speculative as what was measured was WHAT people did. Internal motivation is in this case unproven, there is just a potential correlation.
//> confuses me to hell people taking about error margins and confidence intervals for something measured directly.
