Latest coupon and price update (UTC):
Banggood ($54.99)
Banggood warehouse is located in China. Hmmm… There is no active coupon in Banggood at this moment. 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 $52.15)
