My Allergies Don't Take the Winter Off

I'm always checking prices on allergy medicine and thought the price below had to be a typo. The price for a 365 pill (year supply) of Cetirizine, generic Zyrtec, is $14.99. That works out to $0.04 per pill! The generics at other retailers usually comes out to ~$0.30/pill and brand name Zyrtec is usually ~$0.40/pill. If you're really into the brand name, Costco's price at the time was around $0.30/pill or around what other retailers charge for their generic. The added benefit on top of the great price is the convenience of purchasing one bottle for the year. Most other retailers offer bottles with less than 30 doses. For what?!

 Note: these prices may have changed since I took the picture.
