Square premium has real time shipping cost. Square basic has like an estimated shipping cost. If you have have square basic you need to go to square.online.com, then click fulfillment, then shipping. Scroll down to Shipping Profiles and set your shipping rates. This is where you have to do a little work. On ours 1 item ships for about 4.70, so we set 1 item at 5.00, 2-3 items we add 1.00 so the rate goes to 6.00. We keep doing that until we reach 10.00 we cap at 10.00. I’ve attached a photo to show you how we set ours up.
