WHERE CAN I BUY DISTILLED WATER IN KRAKOW, POLAND?

Hi,

Does anyone know where in Krakow can I buy distilled water? Or the name of the companies that produce it?
I very much appreciate your help!!!!

I think you can buy it at petrol stations.

Thanks for your answer, I don't speak polish and I would like to find the water companies in Poland which make distilled water, to contact them directly. I will need a regular supply for medical purposes.

Thanks for your help again!!!
