The best place to get it from is the same place window cleaners get there water from, there is usually a pump station that sells pure water, check your local area for one

Rainwater, needs a little sanitation though

Here Distilled and 'filtered' water by the gallon are the same price...about $1.10 per gallon.
I did check out the refill stations at our local places...a 5g refill will run you $5.99.
Which makes it more expensive to buy/refill than it does just to buy jugs. That of course makes no sense since there's the individual cost of the gallon jugs and all.

Yeah, if you want dust blown all over the place

Hydro-Logic RO-150 or the Micro 75 system is going to be your best bet on cost. The only other thing you will need is a 5 gallon bucket and a basic aquarium 1/4" float stop. Don't waste your time buying RO/Distilled water you will end up spending far more than what you would on a system not to mention it's more of a hassle.

+1 for the RO system advise.
I bought a Hydro-Logic RO-200 (overkill but fills faster) and I'm still on the 1st membranes/filters YEARS later. I still have a very low PPM and my city water is very hard. I bought the flush kit for it even, never hooked it up. I keep a Brute trashcan (food safe) with a float-valve attached and then run it off a sink adapter. It has more than paid for itself - easily.

btw - I did buy the upgraded KDF carbon filters btw, those seem to be worth it.
The 1 thing I found is that mine is so old, you can't get the replacement filters anymore. Now's it's a RO-150/300 model and I'm not clear if the replacements are drop in equivalents for the older/original model and if they fit & work fine.

How much are you watering?
I use around 10 gallons daily, and with the hydrologic ro150 my filters require replacing every 3-4 months.

Only a couple gallons a day, small time here. 
But still, several years on these filters/membranes and last time I did a PPM check it was very low from what I remember - lower than I had expected given their age and how hard the water is here.

I got an ro unit from bulk reef supply for the same cost as a hydrologic 150 but it’s a 5 stage. I have chloramines so I needed the extra carbon block. If your just using for your watering water then they have really good prices and reliable units. If it’s just a humidifier and you want to make the water a little less harsh in your humidifier then just get the hydrologic small boy.
