@trishanna, a lot depends on which stores are available in a person's area. I can't name names other than my own Hy-Vee but there are three others in my town which do deliveries.

One is slightly more expensive than the so-called high-volume stores and I pay a few pennies more per item from my own store than I would a "cheaper" store. On a fixed income I have to adjust other expenses as a result but I'm willing to do that and glad I can.

One of the stores here I wouldn't buy anything from if I was starving. One time I ordered zucchini and they sent cucumbers and they sent terrible produce the rest of the time.

I eat no meat whatsoever so no issues there and I bake my own bread or buy white bread with no phosphates listed so no issues there. But until I found the right store for me I really struggled so I can relate to your difficulties.

If there's not a store in your area which can deliver good quality whole foods, pre-made meals certainly are an option. A friend is diabetic with cardiovascular issues, though no renal disease yet, and subscribes to a frozen-ingrdient dinner service on a diabetic plan and has lost 40 pounds and is now off all but one diabetic meds and has been able to go off a blood pressure med and a heart med. I just emailed my friend and asked for the name of the company he uses. It's BistroMD. http://www.bistromd.com. I think it's fairly expensive so he only uses one of the meals each day and "fills in" with oatmeal or cereal for breakfast and sandwiches and fruit for lunch.
