Coffee-mate is on sale B1G1 at Walgreens this week (2 for $2.49). The have been reset so print two (you might even be able to print four per computer by using your browser's back button!) and use two coupons for each two bottles of Coffee-mate you purchase and you'll get them both free, with possible overage!
There are also which would make these $0.25 per bottle after the coupons and sale.
I've heard some Wal-Mart stores sell a smaller bottle of Coffee-mate for $1.50 so if you don't have a Walgreens nearby, you might check Wal-Mart.
