Latest coupon code price check (UTC time):
Banggood
Banggood warehouse is located in Europe 
. So I have checked for active coupons (all category coupons and old ones), but there was no working coupon in Banggood. I don’t know if this is a good price – number of records in my database is too low!

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: $17.99.
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)).
