I have checked all old coupons and price is 61.2 USD for Bathroom Sink Sensor (in Banggood). Just check coupons out (with price alert and history). What is best price?
Latest coupon and price update (UTC):
Banggood (61.20 USD)
Banggood warehouse is located in China. As you can see I didn’t find any active coupon for this product right now… What about the price? Hmmm, price is higher than average (which is 33.99 USD right now), so better set price alert down below…

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): BG30c56c, Cuponation9, BG9cbbf9, BG8ReviTrage, BGcoupon8off, BGGutscheine, BG8OFFCOUPON, TTBLACK5, BG7d7282, BG6e326e, BGSCHOOL8OFF, BGCAPITALOS8, BGCOUPERT8, BG8FORMULAMX
(there’s a little possibility that old coupon will work)
