Billing and Shipping FAQ'S

Domestic Orders 

Our shipping department is able to ship to street addresses and PO Boxes within the United States. The purchaser is responsible for providing the correct mailing address. Please be certain your address is correct regardless of your ordering process, before finalizing your order. We cannot be responsible for goods delivered to the wrong address.

Order Processing Times

We typically ship Monday-Friday and try to process orders within 1-3 business days (except holidays and weekends). Orders submitted on weekends or holidays will process the next business day.  Occasionally, especially during sales, order processing can take longer. 

All packages, unless otherwise stipulated, once processed, are shipped via United States Postal Service First Class Mail. This service provides delivery confirmation for all of our orders. All delivery times are estimated by the USPS from the time your order leaves our warehouse.  Transit time can take 5-7 business days from the time the order leaves the warehouse. 

Tracking Your Order 

When your order is ready to be shipped, you will receive a shipment confirmation e-mail. The majority of our orders are shipped within 1-3 business days after the order has been placed and will arrive 7-10 business days after it is shipped. The e-mail will contain shipment details and your tracking number.

If you attempt to track your package within 48 hours after it is ordered and there is no information available about your package, this is because the carrier has not scanned your package yet. When the package is scanned you will be able see the tracking information. Please allow at least 48 hours for the carrier to scan your package. If you still do not see tracking information please call customer service at at 1 800-481-1938

International Orders

All packages, unless otherwise stipulated, once processed, ship United States Postal Service Priority International.

The purchaser is responsible for paying any applicable taxes or duties that may apply. We do not calculate or collect taxes or duties from you. It is the purchaser’s responsibility to check country and local regulations and policies of the receiving country and abide by those. It is the responsibility of the purchaser to be sure the Customs Department permits the shipment of our products to your country and what the duties or tariffs may be upon delivery. We will not provide a refund on the shipping of the package if you refuse the package or if it is refused by customs due to regulations and taxes or duties. If the package is seized by customs for any reason and the package is not returned to us, we cannot issue a refund.


Canadian shipments may be subject to goods and services tax, provincial sales tax, duties, or handling fees based on the product, amount of purchase, and the province.

All shipments to Canada will be shipped via the U.S. Postal Service. Additional handling fees on products may be charged by the local post office. 

Lost or Stolen Packages

Delta Labs is not responsible for lost or stolen packages that have a confirmed delivery to the address entered for an order. Upon inquiry, we will confirm delivery to the provided address, date of delivery, tracking information and shipping carrier information for the customer to investigate. 

Incorrect Shipping Information  

If a package is returned to Delta Labs due to an incorrect or incomplete shipping address provided by a customer, the customer will be responsible for the return shipping cost as well as the redelivery cost. Delta Labs is not responsible for packages delivered incorrectly or lost due to incorrect or incomplete shipping information provided by a customer.

Can I change my address after I place an order?

The shipping address cannot be changed on an order after it's placed. Please attempt to cancel your order right way and then place the order again using the correct address. If you're unable to cancel the order, please call us at 1-800-481-1938 to speak to a representative.  Please do not email us, as the email might not be seen in time, and your order will be sent to the wrong address.
