Latest coupon and price update (UTC):
Banggood (12.99 USD)
Banggood warehouse is located in China. I can’t find any active coupons for this product in Banggood. You probably want to know if this is a good price. Hmmm, price is higher than average (which is 11.86 USD right now), so better set price alert down below…
