I am monitoring price for 0-14.0 PH Meter Tester and it is for 12.99 USD now (in Banggood). Price history, coupons and price alert are available on this page. What is best price?
Latest coupon and price update (UTC):
Banggood (12.99 USD)
Banggood warehouse is located in China. I don’t think there is an active coupon right now – at least in my database. The question is – is it a good price? Hmmm, price is higher than average (which is 7.66 USD right now), so better set price alert down below…

Price: 12.99 USD
Old coupons (from the oldest to the newest): BGcb9339, BGGines, BGTools8
(there’s a little possibility that old coupon will work)
