Jan, on that topic, are you aware of this thing of becoming an "importer or record" if you buy more than three things per year from Amazon or similar sites. It's a new thing that SARS has started doing this year.
"According to reports from TimesLive, SARS confirmed that citizens who bring in more than three import consignments per year will need to apply for an importer’s code.
The regulations have been in place since 2013, but are reportedly only now being enforced – with the reports of the crackdown starting in April 2018.
According to the SARS website, to register as an importer you must provide several personal and identifying documents, along with a certified copy of a close corporation registration or a company registration.
....
One of the ways to buy goods from international markets such as the US and not cut into your import quota is to use an import service from a local ecommerce store.
This sees a local retailer bring your order into the country under its own importer’s code, delivering it to you as if you had purchased it in South Africa."
