Latest coupon and price update (UTC):
Banggood ($17.99)
Banggood warehouse is located in China. So I have checked for active coupons (all category coupons and old ones), but there was no working coupon in Banggood. I think you want to know if the price is good. Maybe there’re no more promotions for this item, because current price is higher than average (which is equal $14.17)
