Latest coupon and price update (UTC):
Banggood (22.99 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. Isn’t it too expensive? From what I can see this price is higher than average price (17.99 USD).
