IUI drug cost

Just met with a fertility specialist. They are recommending IUI with Clomid, and Follistim, Gonal-F, and Novarel/HCG. They are using Alliance RX Walgreens Prime pharmacy since I have BCBS insurance. Clinic said they authorize the RX, pharmacy calls me with details, then drugs get shipped to me.

Does this seem normal, or should I shop around? Does it even matter or will my insurance leave me the same copay regardless of which pharmacy?
