Script Unlock is a free service that helps patients compare cash prices for prescription medications from licensed, verified pharmacies. Users upload a photo or file of a prescription, then pharmacies can respond with their own price for the specified medication, strength, and quantity. Patients compare the offers, choose the pharmacy that suits them, and pay that pharmacy directly when collecting their medication. No payment is made through Script Unlock, and the service says it charges patients no fees and requires no credit card.

The process is designed to make pharmacy pricing easier to compare while keeping the patient in control of where to fill a prescription. Prescription details are shared only with pharmacies that have been verified. Script Unlock manually verifies pharmacies, including veterinary practices that compound medications, before allowing them to submit bids. The site also invites users to refer local pharmacies, helping them connect with patients seeking savings.
