If there is an A&P grocery market with pharmacy, call and ask them what their price(s) are on your med., awhile back there was quite a difference from Rite Aid,CVS and a locoal private/family owned pharmacy (they were the highest),CVS was next highest, Rite Aid was better but A&P or in some states is called Superfresh, came to be the lowest price for a certain med my dog needed, it was generic though, generics can save money too, if your body is fine with it.
Generics are cheaper, due to the fact when a pharmaceutical companies patent runs out they sell them to labs, that just make the stuff, do not have to have researchers because the patent they purchased has the "recipe" the company making the generic doesn't have to pay researchers to create the new meds,adds,etc. It pays to call different grocery markets that have pharmacy connected with their stores.
Lots of luck with this
