Latest price update (UTC time):
Banggood ($12.99)
Banggood warehouse is located in China. There are no active coupons for this product, but the price is pretty low isn’t it? Is it expensive? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal $12.79)
