As in, pretty much all sellers absolutely refuse to ship directly to Nigeria at their own discretion since eBay doesn’t even list the country as a shipping destination (usually excluded countries are listed like: Afghanistan, Syria, Iraq, etc). where the reasons are already given and obvious, but Nigeria is not cited amongst them, why is that?
Perhaps, but most Western sellers just see the whole of Africa as a “dangerous” place to ship to, just like the Middle East, etc. They might be afraid that factors outside of their control will prevent delivery, and in which case eBay is aggressively pro-buyer in such disputes.
Personally, I do not ship internationally at this point and have seen many friends lose thousands shipping and item around the world, only to get charged an obligated refund 5 months later when the buyer says it was never delivered to their 7th floor coffin home in Taiwan.
