I juggle pharmacy prescriptions every month for my triplets allergy and asmtha meds....I have lots of choices to do this with so I'm lucky but it does take some effort. I don't think anyone is losing money around here because most people are too lazy to go to the trouble. My husband is one of the lazy ones for his asmtha meds. I have to nag to make him let me do it. Also if you think about all of the prescriptions for antibioitics etc that Dr. write and people stop on the way home to fill...they don't even have a coupon with them....(I of course keep a stash in my car!!!) or even think about it. They just want the drug now. My pharmacy never cares whether they filled it the two months before. If they start caring....I'll just take it to one of the other 10 places!!
