2. ($23.99): BGDEFO313

Additional Banggood coupons: first page and second page
Old coupons (from the oldest to the newest): BGDESE313, BgcLuBofErtA10
(system checks these coupons on every price check (like once per 24 hours), but you can check them out anyway)
Price history and price alert
It doesn’t make sense to generate price history chart, because there is one price record which is: $22.99.
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)).
