I need to find the best way to link my current WP site to UPS and USPS so that shipping is automatically calculated.
I have done some research and found that you need licenses and the API links to their systems for this.
Are there no free options for WordPress? I believe that Magento had free options, but can't find the same for WP.
If I do have to purchase, I would probably buy a multi-site license. So, if I NEED to buy, what are my best options.
I appreciate the help.
