According to my DB the lowest price is $37.82 for 5.8G 48CH 4.3 Inch LCD 480×272 FPV Monitor (in Banggood). Basically copy coupon, view price history or create e-mail price alert. Best price?
Latest price update (UTC time):
Banggood ($37.82)
Banggood warehouse is located in China. Too bad there’s no coupon right now in Banggood. The question is – is it a good price? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal $27.99)
