get sephora's jumbo eyeliner pencil for $1.
Right now on Sephora.com, two of their Jumbo Eyeliner Pencils are $1 each. The colors are gray and pink / gray, and they're extremely soft and smudge-friendly - great for a subtle smoke-eye effect, which you can do either on both lids, or just in the corners if you're trying to do the "I just woke out of bed and had amazing sex" look. (Yes, this look exists, although you've got to be careful because if it's too messy, it goes past smoldering and straight to "I have a hangover.")
If you want to risk the $1 or $2 and give it a try, click through before they're all gone...
