We don’t have a Harvey’s unit, but our softener was supplied with 4 blocks (ie 16kg) of Harvey’s block salt. I’m about to run out and have a prime account so ordered from Amazon prime 6 blocks (24kg) at £27 inc “free” delivery. Works out at £1.125 per kilo.
Is that a good price? Or can I get it cheaper elsewhere? Is all salt the same, it is it worth sticking with Harvey’s.
