Two Walgreens pharmacist advise me if it is a schedule 2 prescription they will only accept manufacturer coupons. With that being said check out Blink com. do you compare the prices with the coupon or the price the pharmacy is offering you.
In speaking with various pharmacist, (Walmart, CVS) they say is it because the companies are not paying the difference to them.
As far as my option with Walgreens (at lest in south. Miami) # they have issues filling anything that is a schedule to even Tramadol.
My experience also is depending upon who is working, they may or may not accept your coupon. IDK but when it comes to Pharmaceuticals reps, doctors with kickback benefits. They are Pirates, but do check out Blink.com
remember to compare the prices.
I hope this helps you a Lil bit. Kind regards, Annette
