Latest coupon code price check (UTC time):
Banggood ($13.99)
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. The question is – is it a good price? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal $11.99)
