I've looked at about 10 sites for an answer to this question and it's always the same "With insurance it's around $3.60 a pill." Well good for you and your insurance. I'm glad you have it. MOST PEOPLE DON'T. and for all the "great unwashed" that don't the cost is almost $10.00 a pill and be careful. Don't get into Lunesta unless you can keep paying for it because it's adictive.
I can see the headlines now " Man caught robbing Stop and Go says he did it to get Lunesta as his insurance quit paying because he was in the "donut hole." :-)
