Latest coupon and price update (UTC):
Banggood (300.49 USD)
Banggood warehouse is located in China. I couldn’t find any coupon for this product on latest product update. Isn’t it too expensive? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal 240.74 USD)
