Forgot my Clinique mascara last trip, ran in to a CVS, picked up Revlon's LashFantasy after vaguely remembering a TV ad about it. It delivers! Your lashes really do look longer. It's the one with the "conditioner" in the white tube on one side, the regular mascara on the other. It was about $11.

I am also a huge fan of Origins "Out of Trouble" mask ($18). It is great after a long flight when you need to go out and don't have time to shower. You feel refreshed and it has a kind of aroma-therapy quality to it. Very relaxing.
