Latest price update (UTC time):
Banggood ($20.69)
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. From what I can see this price is higher than average price ($19.49).
