I've never even known, because we always just paid the deductible and never saw what the regular cost was. Now, we switched to a high deductible insurance and while we haven't seen anything too high yet, I just paid $102 for my PRENATAL VITAMINS!
Enbrel for me too...it's about $1200 per month w/out insurance. I pay $35.
I have 2 kids on Advair - before the ins. they are $92 each - after ins. they are $50 - not much of a difference but Thank God for Ins.
