I know it's not a good or crazy deal, just sharing experience.
I wanted to try the process of buying a gpu on Taobao (china), since those prices are really good (vs my local market that's Ecuador).
Sadly customs didn't like it and had to pay another 120$ in fees + shipping.
The thing that really surprised me it's the condition it's a 9+ years GPU from China, probably from the mining era and looks pristine, no rust no scratches looks awesome, since it's was a test I sold at a lost for 180$ (1080ti still sold for +200$ In here so really sold in a day) and now I'm ready to try a V100 modded with 3090 heatsink for 200$. For personal use.
But I think there's a market in my country for this kind of GPU I just need to find a way to get china level prices with low custom fees.
