We just got word this morning, but if you’re interested in 20% off at Sephora today, head over to the Sephora Union Street at 2083 Union St. San Francisco, California, 94123. This offer is only available for today, October 23rd only from 7-9PM tonight. Don’t miss out! Overall, that Sephora store is generally very busy and packed with beauty seekers that have just finished their cycling class or cruising one of the most popular areas in San Francisco; the Marina/Union St. There are 4 beauty stations when you first enter and staff is pretty welcoming, especially consider that each woman walking in has something in mind they want to get and will likely purchase more than what they want!
