Banggood
Banggood warehouse is located in China. There’s only 1 record in my database, so I have no idea if the price is OK. I found coupon for you. Check this out.

Price history and price alert
There is only one database record (it was for $16.08), 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)).
