Affordable Diabetic supplies in North Carolina?

I was wondering if anyone knew of ways to save on insulin? I have heard the same products in other states is cheaper. Also, is there any legit insurance that is affordable for a type 1 diabetic with limited resources?
Any information would be greatly appreciated.

Have you checked the prices in Walmart? My son was getting insulin there - considerably cheaper than other places he tried.

Hey, not in awhile. I will look into it. Thank you.
