Terms of Service

The Houston Museum of Natural Science accepts Visa, MasterCard, Discover and American Express.

Please note that once you confirm your order, your credit card will be charged immediately. When you click "Confirm Order" at checkout, you will receive an order number which you should keep for your records. We will also email an order confirmation within 24 hours. Shipments to Hawaii and Alaska might take longer than shipments to the continental US.
