Hello,
I'm building an online store with J2Commerce 6 on Joomla 6, and I will be selling exclusively to specific areas within the Peloponnese region of Greece (e.g. only certain towns/postal codes within the Arkadia regional unit — not the entire regional unit).
Question: Do the Zones/Geozones system or the Shipping Methods support restriction at postal code or town/city level, or is the smallest available unit the "Zone" level (i.e. regional unit/prefecture)?
If this isn't natively supported, is there an official or recommended extension/plugin to achieve shipping/sales restriction by postal code?
Thank you in advance.
