We were plenty psyched enough to learn that MAC Cosmetics (the geniuses behind聽that rainbow ColourRocker lipstick collection) would soon聽join the ranks of our fave beauty brands at聽ULTA stores come May 7, but now, we have even more reason to celebrate.

Thanks to an Instagram clip posted to the retailer鈥檚 page, we know that as of 1pm EST on May 1, the retailer will have a half-price flash sale on MAC products!

As beauty vlogger Laura Lee聽says in the clip, 鈥淚鈥檓 gonna be telling you guys about an amazing flash sale going on.鈥 While the actual sale鈥檚 content will come as a surprise, ULTA gave us a little teaser in the form of the caption (presumably written by Lee), which says, 鈥淵ou won鈥檛 want to miss it!!! It鈥檚 about one of my favorite MAC products besides my own lipstick.鈥

In addition to the mysterious half-price product, the video reveals several of Lee鈥檚 other can鈥檛-live-without MAC go-tos, including the Prep + Prime Fix Facial Mist ($24), the Pro Longwear Paint Pot in Soft Ochre ($22), and MAC Lipglass Clear ($16), all of which we assume will be available to shop for the site鈥檚 big launch.

It鈥檚 happening in a just a few. The clock鈥檚 ticking!
