Latest coupon and price update (UTC):
Banggood ($45.99)
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. You probably want to know if this is a good price. From what I can see this price is higher than average price ($32.99).
