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
(you can check these old coupons out, but these probably won’t work)
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)).
