I have just checked coupons. The lowest price I could get is 11.59 USD for 1 Sensor Module Starter (in Banggood). You can create price alert here, copy coupons and view price history. Best price?
Latest coupon and price update (UTC):
Banggood (11.59 USD)
Banggood warehouse is located in China. There are no active coupons for this product, but the price is pretty low isn’t it? What about the price? Cool, average is 11.82 USD, so current price is lower!
