Latest coupon and price update (UTC):
Banggood ($149.99)
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. Well, is it a good price anyway? This price is higher than average price ($143.57) for this item.
