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): BGToys1, BGRCT10
(these coupons are old, so probably won’t work)
Price history and price alert
It doesn’t make sense to generate price history chart, because there is one price record which is: 36.99 USD.
You can set price alert (for Banggood).
