I picked up my 3% Sod Chlo from CVS today. The box contains 50 vials--each contains 15 mL. I only use 4 mL per treatment so I'll have to just use what I need, put the rest in a zip lock bag till the next treatment. This is not ideal but under the circumstances it is something I can work with. There was a time last year that the same thing happened. By the way the HyperSal that I've had to settle for over the last several months cost almost $40. (each time it came with a Pari neb kit--which I did not need but had to pay for it.) What I picked up today was $3.27.
