It's possible those you see coming out with tons of meds have applied for and received medications at a free or reduced price.
I get 3 meds for free from the manufacturer, they are Cymbalta, Insulin and Lyrica. The other meds I'm on are on the $4-10 list at Wal-Mart.
You can ask your pcp or any doctor/clinic about applying for prescription assistance.

Good luck to you!
