Do you ever have discount codes or sales?

You are here:

We don’t typically offer promotion codes, but we’re always happy to help figure out the perfect combination of Cubelets kits and individual blocks for your kids or classroom! How many students or users will be building at once? What age group are you purchasing for? Contact us at

Our Educator Discount of 20% is already included in the price of all of our Cubelets Educator Packs.

If Cubelets still seem out of your price range, check out the Cubelets Cycle Program. This program was designed specifically to make Cubelets more accessible for all kids in all schools. All you need to do is reserve your Education Pack (includes Bluetooth Hats), select the grade level of lesson plan book that you’d like to receive, and when you’d like it to arrive. Then you can use the Cubelets and lesson plan book for 30, 60, or 90 days, which is plenty of time to complete a full unit with Cubelets!

You might even choose to share the Cubelets Set with other teachers at your school or in your grade level. Battery Cubelets hold charge for 6-8 hours of continuous use; and one hour per class per day can quickly make the monthly cost well worth it.

Do you have older Cubelets or the classic Bluetooth Cubelet and you’d like to make an upgrade? We collect nonworking Cubelets to refurbish or recycle them. We’ll then send you a discount if you’d like to purchase the Bluetooth Hat or new replacement Cubelets. Contact us at to participate.
