I have checked all old coupons and price is 349.59 USD for Malahit-DSP2 2.40 2nd Generation (in Banggood). Price history, coupons and price alert are available on this page. What is the best price?
Latest price update (UTC time):
Banggood (349.59 USD)
Banggood warehouse is located in China. Is it a low price? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal 323.99 USD) There’re 2 active coupon codes available! Awesome!
