I have checked all old coupons and price is 77.46 USD for HAIKELITE HK05 5x SFN60 30000lm 1000m Flashlight (in Banggood). Price history, coupons and price alert are available on this page. Best price?
Latest coupon and price update (UTC):
Banggood (77.46 USD)
Banggood warehouse is located in China. I don’t think there is an active coupon right now – at least in my database. Isn’t it too expensive? The average price for this item is 81.77 USD, so I think it’s a good price!
