If you are Costco Member head on over to request your FREE Sample of Crest Pro-Health Multi-Protection Rinse! You will need to enter your Costco membership number, your mailing information, and answer a few short questions.
Here is the fine print:
Please allow 4-6 weeks for delivery. While supplies last. Available to U.S. Residents only. Limit one sample per household. You must be 18 or older to receive this sample.
I love these small mouthwash samples for packing on short trips, or even tossing in your gym bag!
