Please note, USPS and UPS may take 24-48hrs to update shipment tracking, but rest assured we will do our part to get your order on it's way to you as quick as possible. You will receive an email from us if there is an unforeseen delay that may cause your order to arrive later than expected. Please note that all transit times are listed in business days. This excludes Saturdays, Sundays, and most holidays. 

If your shipment is late and you think there is a problem with the delivery, we encourage you to contact us via email. We will investigate and respond in a prompt manner.

Within the Contiguous 48 States: Standard shipping is just $6.99 per order and FREE for orders over $50. Standard shipments may be delivered by either UPS or USPS and we cannot determine which of the two will ultimately deliver the package. Occasionally, UPS will deliver the package to the local post office and the post office will then deliver it to your door. Transit time is typically 2-5 business days. You will be provided with a tracking number via email as soon as your order is shipped.

You may choose to upgrade your shipping to Express 2-Day delivery once you are ready to check out. Depending on the time of day the order was placed, your order will arrive in 2-3 business days. All transit times are listed in business days. Please note our standard Express 2-day shipping charge may not be adequate for large orders or orders to certain destinations. We will reach out to alert you about potential additional shipping costs, and will not charge your payment method until we resolve any confusion. The additional shipping charges for upgraded air shipments will be calculated based on the weight of the products you purchase and the destination. Please note that if you live in Hawaii, Alaska or a U.S. Territory you must select "USPS Priority Mail" as your delivery option.

Hawaii, Alaska, and US Territories: If you live in Alaska, Hawaii, or a U.S. territory, your order will be sent via USPS Priority Mail. USPS Priority Mail usually arrives within 2-4 days, however, it is not guaranteed and it cannot be tracked until it is delivered. While we do our best to accommodate our customers in these areas, we cannot offer our standard $6.99 flat-rate for these orders. Orders greater than $50 will qualify for free standard USPS shipping and orders less $50 will be charged a $12 flat rate.

P.O. Boxes: If your delivery address is a United States P.O. Box, your order will be sent via USPS. Please note that because UPS cannot deliver to P.O. boxes, orders not qualifying for standard shipping rates may be more expensive. Having your order sent to a place that accepts both UPS and US Postal Service is recommended if you wish to keep your shipping costs low.
