Our Co-op is determining next year’s courses. Why? We want to have plenty of time to select the textbooks and shop for decent prices. I’m buying copies of Chemistry and Physics to teach Apologia’s Young Explorers course next year. I like to have the textbooks on hand for the classes. My target price is $10. We’re planning three new middle school courses. Right now, we’re buying a bunch of used textbooks for U.S.Government and American History. We need time to determine the textbooks. Think about your classes for next year. You’ll have loads of time to shop for decent prices. BTW ,y favorite sites for used textbooks are Thriftbooks, eBay, and Amazon.
