We are about to go live on our new site and we encountered an issue with integrating with Stamps.com. We got everything connected, but when someone does a pick-up order, it still sends the order to Stamps, even though a label is not needed. Has anyone encountered this issue and figured out how to only send orders to Stamps if the customer selects the shipping option at checkout? I've contacted both Stamps.com and Shopify and neither seem to know a solution. Thanks!
