Sugi Pharmacy Group's system failure nationwide Is "Leap Day" the cause?. At approximately 1,300 dispensing stores across the country, the computer systems used to register prescriptions and pay bills are no longer usable.

Pharmacists at each store will, at their own discretion, dispense the medicine for emergencies and have the patient pay for the medication at a later date. The group believes that the cause of the disaster is that February 29th falls on Leap Day, which occurs once every four years.
