I have just checked coupons. The lowest price I could get is 12.99 USD for Mini USB Handheld Fan With Digital Display (in Banggood). Just check coupons out (with price alert and history). What is best price?
Latest coupon code price check (UTC time):
Banggood (12.99 USD)
Banggood warehouse is located in China. There are no active coupons for this product, but the price is pretty low isn’t it? Good or bad price? Hmmm, price is higher than average (which is 12.16 USD right now), so better set price alert down below…
