I believe that most walmart and publix water machines are only RO. Reason so is that DI water is not good for human consumption. It's so pure that if consumed by humans, it will actually draw nutrients from your body. At least that's what I've read...
Hopefully we'll get some more responses to confirm or otherwise...
How big is your tank? An RODI is a very good investment...

Close but no cigar.
The 'nutrients' can't easily cross cell membranes, so instead the water enters the cell in an attempt to equalize the dilution ratio on both sides.
This can lead to what is called 'osmotic shock'. A potentially serious, even deadly, condition where the cells may rupture.
When this happens on a large enough scale, is where it can get serious.
+1 exactly correct. This will also happen if too much of any water is consumed in a short amount of time. Water is very permeable through cellular walls and even tap water does not have anywhere the same ionic composition of intracellular fluid. The intracellular chemical balance is thrown way off and cellular misfunction or damage can result. Remember the poor guys that died by being forced to drink gallons of water during hazing?
As far as RO and DI offerings, I actually got to talk to a guy that services those machines. Some really do offer DI, sometimes at a slightly higher cost per gallon, but you never know when the resin has been depleted. He said most give only RO water due to it being fairly cheap to produce.

As mentioned, your LFS will have RO/DI and be far more attentive to selling you water that has 0 TDS. Wal-Mart or Publix is just filtering out the big chunks and selling you water that likely has some level of TDS.
You want water that has 0 TDS 100% of the time. The best way of getting that is through your own RO/DI system. Second best, LFS. Last resort, walmart/publix.
Furthering the discussion on RO/DI and the human body, are there any known issues in using RO/DI on the skin?

You are always better off buying your own ro/di filter. As others have mentioned, anything out of your control is an unknown. To the initial startup of an ro/di filter may be expensive but will save you a bunch of money down the road by saving you time and money of having to buy it else where. I don't know about you but carrying water jugs from the store to the car the. From the car to the house don't sound like too much fun. If you do decide to get your own ro/di unit, do yourself a favor and get one that is at least 150 gpd. Anything else your just wasting A LOT of water (waste water from the unit) and time waiting for water. I can't imagine waiting 24 hours for just 50 gallons of water.
Bulk Reef Supply always has very dependable solid units that get you to 0 TDS for a pretty cheap price. It will pay itself off so quickly in gas to the LFS/Wal mart and the cost of water. And you get piece of mind. Also, if it's just for hobby use, those filters can last years before you leave 0 TDS
JeF4y, there aren't any issues that can arise from contact with RO/DI water compared to any other water. Drinking RO/DI water is also not dangerous to the body. It only is when consumed in really large amounts in a very short amount of time and that goes even for tapwater. Skin cells are pretty water resistant compared to other tissue types inside the body. The outer layers of skin arent even alive. Oil based products are usually readily absorbed through skin membranes though.
Pure water is pretty interesting. It wants to have stuff dissolved in it and as such can be a decent solvent (but not to human tissue). A LFS uses RO/DI water to clean their tile floors. No soap is even used when mopping. I couldnt believe how clean the floor was compared to tapwater.
