Plenty of items on eBay are just people who buy from China directly and mark up prices.
If it is likely made in China and I don’t want it quickly, I’ll buy off aliexpress. That said, alibaba wanted me to upload photo ID which I noped out of.
Temu started spamming my email address when I’d never used them. The unsubscribe link went to their website said to adjust your account settings if you didn’t want spam… I never created and account and avoided them completely following that.
