Latest coupon and price update (UTC):
Banggood ($34.99)
Banggood warehouse is located in China. I don’t think there is an active coupon right now – at least in my database. The question is – is it a good price? Hmmm, price is higher than average (which is $30.17 right now), so better set price alert down below…
