Latest coupon and price update (UTC):
Banggood (54.33 USD)
Banggood warehouse is located in China. Hmmm… There is no active coupon in Banggood at this moment. I think you want to know if the price is good. Hmmm, price is higher than average (which is 45.44 USD right now), so better set price alert down below…
