Banggood ($28.99)

Banggood warehouse is located in China. So I have checked for active coupons (all category coupons and old ones), but there was no working coupon in Banggood. What about the price? There’s only 1 record in my database, so I have no idea if the price is OK.

Price history and price alert

Well, you won’t see price history chart, coz we have only 1 database record for this item (and price was $27.99).
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)).
