Banggood ($52.99)
Banggood warehouse is located in China. I don’t think there is an active coupon right now – at least in my database. Is it good price? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal $49.49)

You can set price alert (for Banggood and Aliexpress (only if product name will be the same as on Banggood and I will post it on social media though, so it’s more like Banggood price alert)).
