If your store supports and you’ve enabled live or carrier calculated shipping rates, they will be used for orders of warehouse items as well. The rates will be calculated based on the weight of the product and the destination address.
If your store doesn’t support live rates or if you’d prefer to use flat rates instead, you can calculate them using our flat shipping rate calculator. You can find it under the Pricing tab of the Warehouse section in your dashboard. Choose the Printful warehouse where your product will be shipped from, enter the dimensions of the product (its weight, height, width, and length), and you’ll see what the flat shipping rates for this product would be in different regions.
