You may return any unopened or partially used items within 30 days of delivery. We can issue you a refund or store credit for everything except a 5% restock fee.
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).
Request a Return
If you need to return an item, please Contact Us with your order number and details about the product you would like to return.
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 used, shipping date estimates may appear on the shipping quotes page.
Once you place your order, you will receive automatic email updates to inform you of the status. When your package ships, you will receive a shipping confirmation email that includes your tracking number.
Within the US: There is a flat rate of $6.95 shipping per package. If your order is $150 or more, we will waive this fee and you receive free shipping.
International: To determine the shipping cost to your location, put the item in your cart and click to the checkout page. When you have entered your address, it will calculate the shipping price for you.
Please also note that the shipping rates for many items we sell are weight-based. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound.
International Shipping Regulations
We can ship internationally, but please be aware these shipments may take weeks, and may get caught in customs. Although we make very effort to clear customs, we will not be held liable if your package does not clear customs. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.
Some of our lab testing kits do need to be back at the lab within a week. If you live in a more rural area with slower shipping times, please check the notes on the product page and check in with us to determine if this will work for you. If you would like to order a test, please check with your country's policies about shipping medical specimens prior to ordering.
If you have any questions about shipping, please contact us.
