Price history and price alert
It doesn’t make sense to generate price history chart, because there is one price record which is: $34.99.
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)).
