Can I skip a Box or choose the Box I want to get?
Once you subscribe, you cannot skip a Box.
However; you can cancel your subscription at any time. That way you can cancel your subscription before we start shipping the Box you do not want to get and re-activate your subscription prior to us shipping the Box you do want to get.
You can check the shipping schedule of each Box on the STEM Box or Wacky Robots page.
How much does it cost?
The pricing is different depending on the line you choose. The more months you subscribe to, the better price you’re getting.
Wacky Robots subscription (projects shipped every month):
• 1 month: $31.99/Box
• 3 months: $29.99/Box
• 6 months: $27.99/Box + a free Tools pack
• 1 year: $24.99/Box + a free Tools pack
STEM Box subscription (projects shipped every 3 months):
• 1 month: $99.99/Box
• 1 year: $84.99/Box + a free Tools pack
• 2 years: $74.99/Box + a free Tools pack
Can I get a Box without subscribing?
Yes!
Once you click on the "Subscribe" or "Buy now" button, you'll see "Learn about our termed subscriptions" written near the bottom of the screen.
Termed subscription means you won't be automatically charged for renewal once your prepaid period expires.
i.e. You can buy a one-month subscription through termed subscription, and you won't be charged for another box after that one. The box you'll get is the one marked with "Ships: Now" on our website.
So, if you only wish to receive a particular kit, check its shipping date and subscribe to a termed subscription in the month your desired kit is being shipped.
Where do you ship?
We ship worldwide - you can get a Box no matter where you are in the world.
The estimated shipping time is 4 to 6 days, and the best part is that we offer free tracked shipping!
Is this for beginners or experienced makers?
Both!
If you're a beginner, choose our Wacky Robots subscription line and easily enter the exciting world of electronics.
With Wacky Robots, you'll learn about the basics of electronics topics like LEDs, Ohm's law, resistors, capacitors and much more.
