Free Exedrin

I missed out on the previous opportunity to get free Excedrin, but not this time!  Just go to http://www.coupons.com/ .  When you get there, go to "health care" under coupons.  There are 3 different links to request a coupon by mail.  One is for a free Excedrin Extra Strength.  One if for a free Excedrin Migrain.  Third is for $3.50 off Excedrin PM. Unlike most coupons on Coupons.com, you can only request these once per each.
