CVS/Caremark IVF discount Copay?

Hi!  Is anyone aware of a discount or copay card that will work with CVS/Caremark Insurance for IVF drugs? Caremark requires that I order all specialty drugs through their specialty pharmacy if I want to use my insurance. I found numerous discount cards but they require I use a different pharmacy so my insurance will not be applied. We are very lucky to have insurance that covers IVF drugs, however the copay for the meds is close to $2,000. I received quotes for paying out of pocket that were about $3000-$4000. I really thought that my insurance would have a lot lower copays considering my ovidril was only $28. Any information is appreciated. Thanks!!
