My price for proscar thru insurance is $12.95 for 30 days since I can cut it in 5 peieces, I can use it for 150 days. Unbelievable cheap
Now for the insurance pre-existing condition situation, I talked to company's HR and they said pre-existing is not an issue in our plan. So I can use whatever I want. Also, my insurance does not apply discount for propecia so proscar is the only way to go.
Edit: I just found out that Walmart charges $10 for 90 day fillings. woow that will make it cheaper, dunno if they carry Proscar though.
