I have just checked coupons. The lowest price I could get is $16.99 for OLED Display Radio Kit 87-108MHz with 18650 RDA5807 (in Banggood). Basically copy coupon, view price history or create e-mail price alert. Let’s see what best price is ATM.

Banggood ($16.99)
Banggood warehouse is located in China. Coupons for OLED Display Radio Kit 87-108MHz with 18650 RDA5807? Nope, there’re no coupons in Banggood. Isn’t it too expensive? Sorry, but there’s no price history in my database.

Price history and price alert
There is only one database record (it was for $14.59), so you can’t see price history chart.
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)).
