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)).
. I don’t think there is an active coupon right now – at least in my database. There’s only 1 record in my database, so I have no idea if the price is OK.
