Price history and price alert
We don’t have enough records in database to show price history for this item. BTW: We have only recorded this price: $13.99.
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)).
