Latest price update (UTC time):
Banggood
Banggood warehouse is located in Europe 
. I don’t think there is an active coupon right now – at least in my database. I don’t really know if this price is reasonable, coz there’s no price history in my DB.

Price history and price alert
It doesn’t make sense to generate price history chart, because there is one price record which is: $11.45.
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)).
