Wal-Mart said Thursday it will implement its $4 generic prescription program in Florida tomorrow. The rollout comes four months earlier than originally planned.

Wal-Mart said it pushed forward its schedule because of customer demand and requests from Florida state officials. The program was originally set to start in the state in January. It has also been expanded from providing 291 generic medicines to 314. The generic prescriptions will be made available for up to a 30-day supply at commonly prescribed dosages, the retailer said.

“Wal-Mart has again stepped up and is accelerating the rollout of their $4 generic prescription program across the state, said Florida Gov. Jeb Bush. “This program empowers our people to talk to their doctors about accessing these more affordable medications, which can lead to higher compliance rates and better health.

The list of $4 prescriptions is currently dispensed in the 235 Wal-Mart, Neighborhood Market and Sam’s Club pharmacies throughout Florida.
