I also am in your position, Jim, and recently went to the pparx.org site (partnership for prescription assistance - the Montel Williams one). Pretty much every pharmaceutical company seems to give at least some discounts, but some seem to offer them even free. You do have to do a lot of searching of the various links, and each program has separate eligibility requirements, but some beat the discount cards - depends on the med you're taking. As far as I'm concerned, I'll use everything I can get my hands on that's legit (as far as discount programs, not meds!!).
It's work, but it looks like I may qualify to get nexium, a very expensive GI med, free. Right now I just have the discount card for $50 per Rx. Anyway, it's good we can all share resources!
p.s. Williamm - I forgot to welcome you to the Chronic Pain forum of Healing Well. If you want, you can start a thread and introduce yourself more.
