I love the Ulta Days of Beauty. Twice a year, usually starting in March and September, Ulta has a 21 day sale where select brands or items are deeply discounted for one day only. During the Spring 2014 sale, I went a little overboard buying things. Spring 2015 went better. It helped that the sale this year was not as impressive as last, but there were still some great deals. There are also 21 day Love Your Hair Events twice a year, which I will cover later. Check all offers on the special event page.
I highly recommend studying the brochure, which is posted online before the sale. UltaMate members should also get a physical copy in the mail. It is a good idea to plan your purchases ahead of time, so you are ready to strike the moment the deal releases. Ulta runs on Central time, so daily steals are available right at 10pm PST. That usually means steals from the previous day disappear at 10pm, so do not plan to place an order right before bed time if you’re on the West Coast. While the deals have run a little over, Ulta has also cut them off right on time. Some deals sell out quickly, so waiting may not work anyway. The best deals are usually gone when you wake up in the morning from people who started shopping right as the day switched over.
