When I was updating this page, then coupon price was 45.99 USD for SDR Transceiver Receiver (in Banggood). Price history, coupons and price alert are available on this page. Do you want to know what the best price is?
Latest price update (UTC time):
Banggood (45.99 USD)
Banggood warehouse is located in China. I’m afraid that there’s no working coupon in Banggood. I think you want to know if the price is good. Pretty good price – average (48.07 USD) is higher than current one!
