Go here to print off a coupon for $10 off a Patricia Wexler M.D. Dermatology item. It is valid until April 5, 2009. Only available in-store! There are a few items on their website (check it out here) which are listed at $10, so hopefully they would have those same items in the store, so you could end up with a free item.
You can also get a free Zip & Go tote ($10 value) with any Signature Collection purchase online! (I don’t think this can be done in the stores, but correct me if I’m wrong). You put both in your cart and the tote will be automatically deducted! Go here for the details.
