Sephora is offering 15% off 'everything' on 23-24 Nov as their black friday sale. It would be a good time to buy brands that are rarely discounted.
Might have to wait until Friday to see if there are any exclusions. Last year it was both online and in-store.
Free shipping min order for online orders is $55.
It used to be 20% off in the past (in 2016)
Also better if you can shop with a buddy so you can tag team as you wait in the ridiculously long queue to pay
