Latest coupon code price check (UTC time):

Additional Banggood coupons: first page and second page
There were country-specific coupon codes published on Couponsfromchina social channels and price alerts. Coupon price may vary by country, because there’re different VAT rates, shipping cost etc. There is a chance that some latest coupons are still working:
Old coupons (from the oldest to the newest): BG66fc61, hoNEYbGdeAlS, BGRCT10, BGJUNEGSG9, BGRADIORU, BG713a36, BGToys8, BG0a742d
(sometimes old coupons work, so you can check them out (this site checks them on every price update))
Price history and price alert
There is only one database record (it was for $27.99), so you can’t see price history chart.
You can set price alert (for Banggood and Aliexpress (only if product name will be the same as on Banggood and I will post it on social media though, so it’s more like Banggood price alert)).
