Ok makes sense. The shipping is probably more because I was thinking of getting the 250mL’s instead of 100mL (which I think you got Khatti)… we are three sisters and I’m assuming it doesn’t hurt to use it regardless of any skin type.

Sorry to be a pain Stoppit but if you had to guess how long with a 250mL bottle last for 3 girls??
