I don't think that's even legal. Sorry. I'm not sure what you're asking by saying "cheaper than prescription". If you're trying to get adderall without a prescription, that is illegal and a felony. Most states require a hand-written prescription hard copy brought to the pharmacy where when you pick it up you must provide your photo ID. They write down your ID number and you have to sign for it. You can't get adderall online legally. Do you have a diagnosis of ADHD/ADD?
