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.
aliex437 is the code, it is on the page of Aliexpress.
"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 $4. I bought an electric lighter with it per example for 1$"
