After having reflected on the shipping options you wish to offer your website visitors, and having installed any required real-time shipping quote plugin, then go to the STORE/shipping config menu.
Now, select the appropriate options and shipping products that will be made available at checkout.
When using real-time quotes, be mindful of the shipper's service limitations such as shipment weight or linear sizes which are commonly restricted by shipping providers. If none of your selected shipping method is found to be suitable for a given cart, a message will invite your visitors to contact you to arrange for delivery. Then test your checkout mechanism to verify behavior against your expectations.
