I discovered the perfect shade of lipstick last week and it was such a relief. Finally! If only I could have gotten free samples or bought tiny tubes of lipstick years ago, instead of making my way through years of not-quite-right shades of pink, blush, and red.

Now you can jump ahead of this guessing game with a new promotion from E.L.F. cosmetics, which is known for selling makeup for $1 an item. Get $5 of free samples when you make a $20 purchase and use code FREESAMPLES. Unclear when this deal expires.

E.L.F., which stands for eyes lips face, has a few other good promotions going on:

You can get a free mineral bronzer when you spend $15 and use code GLOWING. Expires Feb. 28.

Or you can get 50% off one item when you buy another item. Use code PRESIDENT to get the discount. It's good through Feb. 17.
