Latest coupon and price update (UTC):

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): BG0fe76f, BANGGOODSD, BGdb458f, BG26c0ea
(you can check these old coupons out, but these probably won’t work)
Price history and price alert
Not enough data to show price history chart… $32.99 is the only recorded price. It was not cheaper than that since we have saved it in DB.
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)).
