Latest coupon and price update (UTC):
Banggood (10.99 USD)
Banggood warehouse is located in China. Hmmm… There is no active coupon in Banggood at this moment. Well, is it a good price anyway? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal 10.19 USD)
