When you'll hear back

We reply within two business days. Our support hours are Monday to Friday, 9:00 AM to 5:00 PM. Messages sent over the weekend are answered the following week.

Orders and shipping

Shipping to United States addresses is free, and your order arrives in 3-5 business days. If you need it sooner, express delivery is $3 and arrives in 1-2 business days. Orders are fulfilled from Amazon's US warehouses.

If you need to change or cancel an order, message us as quickly as you can — once an order enters fulfilment we may not be able to stop it.

Schools, teachers and bulk orders

Power of 10 was built in classrooms, and teachers are some of our closest users. If you're buying for a school, a learning centre or a homeschool group and need multiple sets, email us and we'll take care of you directly.

Questions we're always happy to answer

Whether it suits your child's age or level, how it fits your curriculum, what's in the box, or how a particular level works — ask us. We'd rather you buy the right thing than the wrong one.
