Latest coupon and price update (UTC):
Banggood (16.99 USD)
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 12.12 USD right now), so better set price alert down below…
