Bloody good question, not sure.
Just checked juststrings (heh) and my two stock strings are around $13/set (R208), add 16% for vat/levies (+/ R34). The best you'd get it for (ex-shipping) is R242ish? I'd say the prices I saw were around 40-50% more. I know the distributor prices have risen, so retail prices have adjusted. I've been reading that, in general, shipping/ handling costs has risen (up to) 400%.
JustStrings cheapest Intl option is $25 for smaller packages (not sure how many packs) and that'll likely be 6-12weeks in transit, uninsured 😁 But @Bluetone has mentioned he waits for free intl shipping promo's, which I didn't know about! 👍️
