Frequently asked questions
How long until the books arrive?
Books are estimated to arrive 4–6 weeks after ordering. The seasonal deadline shown above is calculated in America/Denver time. Spring preorders can instead select early-August back-to-school delivery.
Can I rush my order?
Preorders can’t be expedited. Every order is estimated to arrive in 4–6 weeks, so we recommend ordering early.
How much does shipping cost?
US Economy shipping is free on US orders of $50 or more. For orders below $50, other destinations, and other shipping methods, taxes and shipping are confirmed after you place the order.
Can I combine different titles to reach the 20-book minimum?
Yes. Mix any of the three subjects and either student format. Free teacher copies will be added during fulfillment: 20 eligible student workbooks earns one, 40 earns two, and so on. You do not need to choose teacher copies or add them to your cart. Teacher copies do not count toward 20.
When do I provide payment or a purchase order?
Place the order online now. No card or other payment is collected at checkout. 3andB emails you after the order so you can provide a PO or arrange payment. You may add an optional PO number while building the set or reply to the follow-up email with the PO.
What comes in the Teacher Edition?
Each Teacher Edition includes complete answer keys and teacher lecture notes, plus access to full slide decks online.
Do the student workbooks include answer keys?
No. Student workbooks do not contain answer keys or lecture notes, so they are ready to hand to students.
Do the books come with videos or slides?
Yes. Every lesson has an online intro video, and each Teacher Edition includes access to full slide decks.
Can I view free samples?
Yes. Visit the free course pages for a chapter preview, chapter answer key, video, and 12 photographed sample pages: Earth Science, Physical Science, or Life Sciences.
Can I return or exchange books?
Because every book is printed to order, returns and exchanges aren’t possible. Printing to order means we don’t pay to store inventory, and we pass those savings on to you.
