Latest coupon and price update (UTC):
Banggood (3.99 USD)
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. Isn’t it too expensive? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal 2.96 USD)
