Not sure if everyone knows this but on the Wal-Mart website under "Pharmacy" there is quite a large list of their $4.00 generic brand prescriptions. Anything on that list (in the correct dosage amount) will be filled for a price of $4.00...and this is entirely separate from insurance...you don't have to have insurance to get this price. There are hundreds of medications on there...some are long term, others are simple, regularly prescribed antibiotics.
Our prescription rates this year for the company I work for has more than doubled...so I printed off a copy of the $4.00 list and leave it in my car. When I have had to take the kids to the doctor for anything I ask my physician to please try to prescribe though one of the medications on the list.
Just this year alone, I've saved over $250 on medications rather than having them filled through our insurance!! It's worth taking a look at!
Some of the meds we take don't have a generic equilivant, but it doesn't hurt to take the list along for a doctor's appointment to see if there's something acceptable on it. Dh takes Lisinopril, ~$50 for 3 month's supply, can get it through Walmart for $4 a month, so there's a savings of $38 every 3 months

Just FYI Target also has this plan, the list looks the same.
