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): BGraton, Cityads2213, BGff5312
(system checks these coupons on every price check (like once per 24 hours), but you can check them out anyway)
Price history and price alert
Well, you won’t see price history chart, coz we have only 1 database record for this item (and price was $19.99).
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)).
