Inventor's Club Monthly Subscription
When you purchase a subscription you'll receive repeat deliveries based on the duration and frequency you select. Our subscriptions include a fixed commitment period of 1, 3, or 12 months. When you sign up, you agree to complete all payments for the term you selected.
Your payment details will be stored securely and you'll be charged for each delivery. During the fixed term, your subscription cannot be canceled. Once all payments for your chosen term have been made, your subscription automatically switches to month-to-month.
Month-to-month subscriptions renew automatically unless canceled. You can cancel at any time once your fixed term has been completed, and the cancellation will apply to the next billing cycle.
You can update your payment method or shipping address at any point during your subscription. Your subscription confirmation emails include a link to your customer portal where you can manage additional details.

Invention challenge

If you are on a 3-month or 12-month prepaid plan, your remaining shipments will continue through the end of your prepaid period. Prepaid plans are non-refundable for unused months.

Totally! Each project is kid-tested and kid-approved for inventors aged 8+. We’ve worked with beginners, advanced builders, and everyone in between to make sure the builds are fun, doable, and confidence-boosting. Kids ages 8+ can work independently on most steps, and grown-ups are always welcome to join the fun!
We love sibling collaboration! Each box comes with materials for one inventor, so sharing is definitely possible, but it may mean taking turns. If both kids want to jump in and build side-by-side, ordering an extra box keeps the fun rolling for everyone.
If ordering multiple subscriptions to ship to the same address, you can adjust the quantity right in your cart. If gifting to different addresses (like a grandparent sending to all the grandkids!), you’ll need to place separate orders so that the subscription will arrive to each mailing address.
Log into your Chompshop account, and click "Manage Subscriptions". From there, you can cancel, pause, update your address, or swap your payment method, all in one place!
Yes! Month-to-month plans renew each month, and prepaid plans renew at the end of each term. You can cancel before your renewal date to prevent future charges.
The Inventor's Club projects ship in a set order. Each one is designed to build on the skills from the month before, so the sequence is part of the experience! That being said, you can always pause your subscription via your subscription portal.
