Latest coupon and price update (UTC):
Banggood (236.99 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. Is it expensive? Hmmm, price is higher than average (which is 232.99 USD right now), so better set price alert down below…
