I have checked all old coupons and price is 76.99 USD for BlitzWolf BW-SHP15 Zigbee (in Banggood). Just check coupons out (with price alert and history). What is the best price?
Latest coupon and price update (UTC):
Banggood (76.99 USD)
Banggood warehouse is located in China. Hmmm… There is no active coupon in Banggood at this moment. Isn’t it too expensive? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal 58.49 USD)
