If you are talking about the PD-A520 then 70 dollars US is expensive. I only paid 35 dollars US for a set I bought new the middle of 2017 and before that in or about 2010. I know some people only trust amazon for shopping and shipping. But I go for whoever is the cheapest for the same product. I've never been stung.
