Coupon AliExpress year 2021 - New social Media users. US$4 off US$5 minimum spend
Found one that is valid until end 2021, some of the old codes also still work.
"You can use the coupon like 8 times if you want, it is not name bound, you only need to login with different social media accounts; TikTok, Instagram, Facebook, etc. Found this coupon on the website of AliExpress. You need to order above $5 and then you get a coupon for $4. I bought an electric lighter with it per example for 1$"
