Latest coupon and price update (UTC):
Banggood (127.99 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. I think you want to know if the price is good. Well, this price is higher than average price (126.99 USD)
