Shipping and Returns
We offer FREE* shipping on all our products to US addresses. All books are shipped via media mail; all experiment kits are shipped via priority mail. We do also offer the option to upgrade to priority shipping for a nominal fee. Please contact email@example.com for rates.
*Note - In order to qualify for free shipping, orders must be placed directly on the website. Purchase orders do not qualify for free shipping. Shipping and handling costs will be added to these orders.
We can ship to virtually any address in the world. However, international customers will be charged for shipping. Note that there are restrictions on some products and some products cannot be shipped to international destinations.
If shipping charges apply when you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page.
Please also note that the shipping rates for many items we sell are weight-based. The weight of any such item can be found on its detail page. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound.
**Refund Policy: We accept returns of our printed books & kits for any reason for up to 35 days after your purchase date. All returns must be in new, unused condition. A 30% restocking fee will be charged to cover a portion of the shipping and handling fees that were not charged at the point of purchase
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases, you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).
If you need to return an item, simply contact us and we will set up the return.
