USPS (Calculated Shipping)
Customers in the United States can now use calculated shipping through USPS, including discounted commercial rates when shipping with a third-party shipping company. When selecting USPS services, a quote will be provided based on the weight and dimensions of each product. Please note that the quoted prices are estimates, and the actual shipping costs may vary depending on how you package multiple items. We recommend confirming the accuracy of the quoted prices with USPS to ensure you are receiving the best possible rates for your shipments.
Simple Shipping
This is our most flexible shipping method and it is recommended if you do not use calculated shipping. Simple shipping charges a fixed price per item and a price for each additional item added to the cart for each destination. You can also add shipping options, which allow you to add additional rates; for example: Standard and Expedited.
Flat rate
One fixed price for all destinations. Use this method if you do not ship internationally and your shipping costs do not increase as items are added to the cart.
