When I sell things on ebay I often use this site: https://www.paypal.com/?cmd=_ship-now
It's a nice way to get a little better rate than going to the post office or using usps.com.
Is there an easy way I can integrate this into my shopify store to fulfill orders I want to ship USPS without copy/pasting the customer name, address, etc?
If not, is there another way to seamlessly create shipping labels for USPS?
Jamie here from Shopify. For merchants in the United States, you certainly can purchase/print USPS shipping labels directly from your Shopify admin. When fulfilling an order, you have the option of purchasing a USPS shipping lable which will automaticaly populate your customer details etc. You can see the full run down in our [Shopify Docs](https://docs.shopify.com/manual/settings/shipping/labels/purchase-and-print). ;
The best way to ship with discounted rates and also perform fulfilment is by using Shopify's default integration with USPS. You can set a default box dimension and then generate label for it. Also, you would not have to copy paste any information as All product and order data would be automatically copied into the label and this would save your time as well. Also, if you want to have special services like signature, insurance, etc, you can opt for the Multi Carrier Shipping label app.
