A tad more expensive but that is a fantastic resource to have. Thanks. I have bookmarked that as a trusted source for water.
I have bought from APC in the past. The DW is cheap enough but if you do not live near the company to collect in person then the delivery costs are an absolute killer.
I always say buy a distiller and produce your own. On a bad run you will produce DW of .0001 ppm good enough for Colloidal Silver and definately much cheaper than APC - even if you wish to go mad and buy their 1000 liter IBC container.
You will recoup the initial cost of the distiller(i use Megahome) in no time at all. They are a little bit more expensive now but still cheaper to make your own.
I have had this discussion with cfnisbet in the past and i am not sure we will agree on my views on making your own DW but i stand firm.
