I have just checked coupons. The lowest price I could get is 519.99 USD for SKYZONE SKY04X OLED FPV (in Banggood). Price history, coupons and price alert are available on this page. Best price?
Latest price update (UTC time):
Banggood (519.99 USD)
Banggood warehouse is located in China. Too bad there’s no coupon right now in Banggood. Is it a low price? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal 485.00 USD)
