As someone actually living in South Africa, why on earth would you mention a specific country in your argument to make yourself not only factually wrong in this case, but also appearing highly misinformed?
Cost of movies in South Africa (Logan as an example, as per
https://www.takealot.com/all?q...):
USD 10,08 (incl tax) - DVD (at supposed 18% discount, converted from ZAR 129)
USD 13,20 (incl tax) - BluRay (at supposed 22% discount, converted from ZAR 169)
USD 27,26 (incl tax) - 4k (at supposed 18% discount, converted from ZAR 349)
Amazon US:
USD 14.99 (incl tax?) - DVD
USD 11.99 (incl tax?) - BluRay
USD 19.99 (incl tax?) - 4K
The only $2 price I have ever seen are maybe bargain bins for older movies, or dodgy pirated DVDs sold by street vendors (which I haven't seen in a few years now actually).
Netflix (now offered here), is charged in USD, at exact same rate as in the US, however, thanks to exclusivity bullshit by local network here, some shows like House of Cards are not available on it.
Based on comments I see on Slashdot, it seems that many people assume that regionalisation and geoblocking of online services is just so that the same thing can be sold "cheaper" in certain markets. Sometimes that's true, for example, I used to work for Blizzard EU CS, and they deliberately isolated Russian servers as they paid lower monthly subs. However, in most non-third world countries, like Australia/NZ, Western Europe and South Africa (not technically 1st world, but for a lot of consumers here, it kind of is), the reason for regionalisation is a legacy of before the internet, where companies got exclusivity arrangements on media from the overseas publishers.
Before the internet, there was value to having these
middlemen who made their money by importing media and making it available. With the advent of legal media distribution over the internet they realised they were becoming obsolete, so they used their pre-existing legal arrangements to prevent publishers from selling direct to consumers in their markets, forcing those markets to still pay them a cut. To summarise, these days consumers in all markets outside of the original publisher's, are essentially paying a kind of "tax" to shmucks from these "distribution" companies for essentially doing nothing.
As you can see above, we here do not really pay less, but also annoyingly, we also get less content available as local distributors often can't be arsed to make some content available here, or the content we get is delayed. Hence people use geoblocking circumvention services such as VPNs to to get around this complete bullshit.
As a final comment, when us South Africans see comments like yours, it reinforces our belief that most Americans don't really know anything outside of their own country.
