Latest price update (UTC time):
Banggood (19.89 USD)
Banggood warehouse is located in China. I don’t think there is an active coupon right now – at least in my database. But wait a sec… Is it a good price? Hmmm, price is higher than average (which is 19.63 USD right now), so better set price alert down below…
