Latest coupon code price check (UTC time):
Banggood ($6.49)
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. Is it good price? From what I can see this price is higher than average price ($3.08).
