I have checked all old coupons and price is $37.94 for BAOFENG DM-5R Walkie Talkie (in Banggood). Basically copy coupon, view price history or create e-mail price alert. What is best price?

Banggood ($37.94)
Banggood warehouse is located in China. Hmmm… There is no active coupon in Banggood at this moment. Is it good price? Hmmm, price is higher than average (which is $23.49 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)).
