Price history and price alert
Well, you won’t see price history chart, coz we have only 1 database record for this item (and price was $5.99).
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)).
