Fresh Earth Food Store offers free delivery to major centers in most parts of the country on orders of R475 or more.
Certain postal codes are however classified as "outside major centers" so they do not qualify for free shipping.
Hints for qualifying for free shipping if your home address is outside of these areas:
Try use your office or work address as the delivery address - this is likely to fall in a major center.
Try the address of a friend nearby who falls under a different postal code.
If you live on a remote farm or outlying rural area, make arrangements to have your shipment delivered to a shop or community center in a nearby town that counts as a major center.
