I've not found any great resources. If you have a doctor, ask for free samples. They typically have lots to give away. When I haven't had insurance I've switched to the less effective insulins (like Regular instead of Humalog or Novolg) because it's less expensive and used the generic Walmart or Walgreens meters because the test strips are less expensive.
Try to contact your insulin companies Patient Assistance Program. All pharma companies have them, many people do not use them. Your doctors office should have some sample contact you primary care doctor and endo both will have insulin. What state do you live in? Many states have additional programs for T1D.
