Latest coupon and price update (UTC):
Banggood ($24.24)
Banggood warehouse is located in China. I don’t think there is an active coupon right now – at least in my database. You probably want to know if this is a good price. Hmmm, price is higher than average (which is $14.09 right now), so better set price alert down below…
