When I was updating this page, then coupon price was $37.99 for LEAVEN K620 Mechanical Keyboard 61 Keys (in Banggood). Basically copy coupon, view price history or create e-mail price alert. What is best price?

Banggood ($37.99)
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. Is it a low price? From what I can see this price is higher than average price ($29.64).

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)).
