Latest coupon and price update (UTC):
Banggood
Banggood warehouse is located in Europe 
. So I have checked for active coupons (all category coupons and old ones), but there was no working coupon in Banggood. I can’t tell you if this price is good – not enough records in my database, so I won’t judge.

Price history and price alert
There is only one database record (it was for $163.19), so you can’t see price history chart.
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)).
