For me these days, it's probably 95/5.
I ordered numerous items, which came via courier, with customs fees consistently around 20% (This is quite high if the item value is low, but anyway).
Weirdly, my DJI battery that I ordered was sent via SAPO and never arrived. It took me a month to get a refund.
I am also well aware that I previously said the customs and duties feed did not bother me that much as it was still affordable for the time it takes to arrive.
The latest order has made me reconsider ordering from AliExpress ever again until they adopt the same billing method as Temu where the fees are included in the price.
A R505 customs fee for a R880 product is just crazy, and at that stage you might as well just pay it.
