Distilled water sources

Hi what is the best distilled water in a bottle? I am concerned that since the bottles in grocery stores are in a plastic water jug that the plastic chemicals would leach into the water... Right?

Also i do not have money to buy my own distiller.

How about the water dispensers at Whole Foods? Are those distilled?

Whereelse can i get clean distiller water with out spending a fortune?

Thank you Tweet
