When your Dr. gives you a new prescription or even an old one, ask if he has samples. Ask for as many as possible. Also ask for baby formula. Sales reps from the pharmaceutical companies leave tons of samples in Dr. offices.

Mom got a 6 month supply of her high blood pressure medicine just by asking.

I do this for my son after he gets his immunizations. Even if it is just a sample bottle of ibuprofen, the saving adds up.
