Starting 1/24/08. I'm probably the last person to learn this, but I'm so happy. The prescription was costing me $50 / month! Ouch! I only found out because CVS has it on their front page ad. Now to find the cheapest place....and some coupons!!!!!!!!!!! There has to be coupons!! I went to zyrtec's website & signed up for coupons. But I want some now.
