Latest coupon and price update (UTC):
Banggood ($34.49)
Banggood warehouse is located in China. I don’t think there is an active coupon right now – at least in my database. What about the price? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal $29.24)
