Tarte will once again be on HauteLook starting at 8AM Pacific on Wednesday, 8/19. Tarte seems to go on HauteLook about once a year, so it's a pretty big event when it happens. You can Google "Tarte HauteLook Haul" to get an idea of the kinds of prices you may see tomorrow. And Emilynoel83 has a great post from 2013 HERE with some of the items/prices that were available at that time.
If you're a Tarte fan, set your reminders now so that you don't miss out tomorrow morning (because I'm guessing that the best deals will sell out pretty quickly). As always, shipping is $5.95 unless you order $100+, in which case it's free.
