What you need to purchase depends on the situation.
Do I need a bundle if I already have a device/clicker? No, you can just purchase a subscription. Use the Clicker Registration link in BOLT and then click the 'Purchase Subscription' button.
What if I am a new student or an existing student who needs to purchase a clicker for the first time? You will need to purchase a clicker AND a subscription code. They are sold as a bundle both online or at the bookstore. The best purchase option for new students is to buy the 5 year bundle which comes with a $10 rebate.
Where can I purchase a clicker/device and subscription? You can purchase them online or at the bookstore. All information regarding clickers can be found on the My Home Page in BOLT. Log in to BOLT and you will see a widget named 'Student Clicker Registration'. Information on where to buy the clicker and license as well as directions on how to register your clicker can be found there.
