When I was updating this page, then coupon price was 80.99 USD for X28 Drone RTF (in Banggood). Basically copy coupon, view price history or create e-mail price alert. Best price?
Latest price update (UTC time):
Banggood (80.99 USD)
Banggood warehouse is located in China. CouponsFromChina software could not find any coupon for this product in Banggood. Isn’t it too expensive? Hmmm, price is higher than average (which is 79.92 USD right now), so better set price alert down below…
