I have checked all old coupons and price is 6.43 USD for HN-CH014 Sticky Gel (in Banggood). Basically copy coupon, view price history or create e-mail price alert. Best price?
Latest price update (UTC time):
Banggood (6.43 USD)
Banggood warehouse is located in China. CouponsFromChina software could not find any coupon for this product in Banggood. Low/high price? Hmmm, price is higher than average (which is 1.10 USD right now), so better set price alert down below…
