Safe acetominophen/codeine dosage and CWE questions are asked almost daily in here, literally. Read through the CWE megathread and/or use the search engine. As amapola mentioned price discussion isn't allowed in BL, but I doubt you'd get more than a couple dollars, if that. Just take them yourself or save them for when you're in pain. With no tolerance they are wonderful for that.
