The cheapest qualifying Advil for me is $6.28. I posted a link to a coupon for $1 off and others below. If you have the coupons from the Sunday inserts for this week (11/3-11/9) there are $3 off coupons for higher quantities which may equal out to a better value.
Just from this post you can get a 50 ct Advil and a $13 movie ticket for $5.28.YMMV
