Now through 9/30, there is a Retailmenot-exclusive code listed on their site for a free Origins Charcoal Mask deluxe sample with any $25 Sephora.com purchase (just enter code RMNCLEAR at checkout on the Sephora site to grab it). You wouldn't know that this code exists if you only checked the Sephora code page (which you should check too), because this is only listed at Retailmenot.com. By the way, they are doing this more and more often with other beauty retailers too, so be sure to do a quick search on Retailmenot.com for any beauty brand you're ordering from, just in case there's a new, exclusive code out there!
PS: Remember in my Burt's Bees Facial Water post how I said that the most popular (and one of the most expensive) essences is by SK-II? Well another of SK-II's essences is one of the choices right now for your three free samples on the Sephora site. You better believe I selected it!
PPS: I swear to you that I have placed more Sephora orders since January (when I signed up for Flash) than in the rest of my life combined. Paying $10 for a year of free shipping at Sephora was one of the best things I've done, and it has paid for itself a zillion times over by now. I mean, shopping their sale page for beauty bargains and not having to worry about shipping fees? Brilliant. I wish ALL beauty retailers offered this type of program. (Well wait, my wallet would hate that. But you know what I mean!)
