as a pharmacy technician i can share with you some websites that give you those "coupons" for your meds!
goodrx is the most well known one, but if i'm trying to find the cheapest price for a patient i compare it to scriptcycle, and use whichever is offering the best price. you just type in the medication (PLEASE make sure you're getting the right drug, dosage, and quantity) and your zip code and they will spit out some offers for you
some pharmacies may have their own discount card to compare to as well!
if you are getting a name brand medication, you can also look at the manufacturer's website to see if they offer any evouchers for you to use too
