Hello,
We have just started our online selling with the free weebly online store through Square. It looks like in order to integrate a shipping calculator for pricing we need to upgrade to either a paid weebly account or upgraded Square account?
Thanks for your question and welcome to Seller Community, @KristinKinsky.
It would not be possible to set up shipping with the free plan, though you can set up shipping rates if you upgrade the site to Professional, Performance, or Premium.
