In the states it goes for about $53-55 shipped online, but if you buy from a hydro store look to pay $82-85 plus tax.what's the cost of the ph 55?
wordwiz said:I got it (just bought it - I like the litmus papers but they are not real accurate) for $60.50 which includes shipping and storage solution from here.
