Latest price update (UTC time):
Banggood ($44.99)
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. The question is – is it a good price? Hmmm, price is higher than average (which is $43.68 right now), so better set price alert down below…

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)).
