Thanks to the internet and thirsty hashtaggers everywhere, there's a day for everything. Honorific highlights from July include National Fried Clam Day, National Paper Bag Day, and on July 29, National Lipstick Day. We'll forgive you if you forgot to observe the two former, but are also here to tell you there's an easy way to commemorate the latter.

To celebrate #NationalLipstick Day on July 29, M.A.C is giving away free full-sized lipsticks—while supplies last—at any M.A.C store or retailer in the U.S. If you are so lucky to nab a bullet, and do know the shades available vary by location, show off your score with the hashtag #MACLipsLipsLips. Maybe you'll want one of the individual shades from the brand's new-this-year lip kits, or maybe you're more in the mood for a classic matte M.A.C Ruby Woo moment (we voted it one of ourtop red lipstick shades of all time). Whatever your lips desire, a full-size tube of M.A.C lipstick will be completely free this Saturday.
