Take lunches to school and work. Give up restaurant eating, if possible. Try alternating meals with a friend or another family. Try to avoid eating meat every day - substitute meat with beans or stir fry vegetables. Buy day old bread products and freeze them for future use.
Preventative measures are usually less expensive in the long run.
Ask your doctor to prescribe generic drugs. Also, shop by phone for best price before buying a prescription. Ask your doctor for sample prescriptions. Follow directions exactly when taking prescriptions or else your drug may not work. Also store drugs in a dry place, not the bathroom.
