Melissa,
If you know of an Avon rep near you it's on sale in the clearance brochure for $2.99. I think there are 5 or 6 colors available.
You can also check the Clinique website to see the next time they're going to have a gift with purchase special in your area.
I LOVE to buy then (Don't tell anyone - because I'm an Avon rep!!) so I can try all the new stuff for nothing! OH! If you're hitting the Clinique counter also check out their Touch Base for Eyes - It's amazing. It comes in MANY colors, it's soft, it comes in a little bitty compact, and you put it on with your fingertip. It will stay on for 24 hours - I swear! I think it's about $12? You can use it as a base for powder shadow or alone. I couldn't tell you which I like better, the touch base or liquid. But you should def. have one or the other in your make up bag.
