Price history and price alert
Price history is not available for this item (not enough database records)! The lowest price was $13.99 though.
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)).
