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)).
. There are no coupons available at this moment in Banggood. I don’t know if this is a good price – number of records in my database is too low!
