Just bring this printable coupon to the Sephora counter in your local J.C. Penney store and redeem it for a free deluxe sample of Buxom mascara. Or, use the code JCPLASH to get the deal online.
This offer is good while supplies last, or until October 22, 2010, whichever comes first. The fine print says they can rescind this offer at any time, so you might want to try to claim yours quickly.
Thanks to Money Saving Mom for this tip.
