I have checked all old coupons and price is 15 USD for LED Program Card (in Banggood). Basically copy coupon, view price history or create e-mail price alert. Best price?
Latest coupon code price check (UTC time):
Banggood (15.00 USD)
Banggood warehouse is located in China. So I have checked for active coupons (all category coupons and old ones), but there was no working coupon in Banggood. Is it a reasonable price for this item? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal 10.19 USD)
