Returns Policy

You may return most new, unopened items within 30 days of delivery for a full refund. If your original purchase included a multi-unit discount (such as buy one get one % off) and your return is for only part of the original shipment, your refund amount will be for the discounted unit price.  Also, a Return To Stock fee of $2.00 per unit will be subtracted from the refund total.  We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).

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, please Contact Us with your order number and details about the product you would like to return. We will respond quickly with instructions for how to return items from your order.


Orders placed prior to 1:00 PM (Central) will ship the same day.

Janson Labs LLC ships Monday through Friday, excluding holidays.

We can ship to virtually any address in the world. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.  Some international destinations may incur a small handling fee.  **Due to international tax rules, we are not able to ship to UK and EU countries at this time.  We hope to be able to ship to these areas in the near future.

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.
