They are legit. I think anyone that says the paperwork is tedious and difficult has never seen the paper work. You put your name, address, DOB, SS#, phone, income and number in household. The doctor does the rest.
Here is what the form from one maker looks like:
So the client can go to Lone Star and pay $30 - $50 a month and they do the work or go to https://www4.pparx.org/en
and they get the client the forms but the client takes them to their doctor who fills it out and sends it in. They can get their free meds a month or two sooner this way.
Either way the senior SAVES MONEY and maybe you use some to make a sale!
