Black Friday & Cyber Monday STEM Toy Deals 2026: Offer Status
Offer status checked November 10, 2026. Black Friday falls on November 27 and Cyber Monday on November 30. LEGO has announced its event dates and a members’ weekend on November 21–22, but none of the official pages checked below was showing a specific Black Friday 2026 product discount on that date.
If you are choosing a STEM gift now, start with the recipient and a shortlist. A sale is only useful if the kit suits their interests, works with their devices and includes what they need. This page separates announced events from general offers so you can compare them without relying on expired coupon codes.
Amazon price drops on our picks
List checked November 10, 2026. Every product below is one we already recommend in a guide, and Amazon was showing it below its own reference price at our last check. These are Amazon price comparisons, not Black Friday offers we have verified with the brands. The reference price is Amazon’s figure, not ours, so treat the saving as a pointer and compare the price you would pay. Prices come from Amazon and can change at any time; a blank saving means the discount has ended since the last check.

Black Friday and Cyber Monday: what is confirmed?
| Brand | Status on November 10 | Official source |
|---|---|---|
| LEGO | Black Friday event announced for November 27–30, 2026, with a LEGO Insiders Weekend for members on November 21–22. No product discount on a building set was listed on November 10. | LEGO US Black Friday event |
| KiwiCo | A subscription promo code advertised with a stated end of November 16, 2026, plus a first-month discount for email signup. Neither is labeled a Black Friday offer. | KiwiCo coupons and offer details |
| MEL Science | No Black Friday 2026 offer shown on the US homepage. The homepage advertised an annual plan at 12 months for the price of 8, not labeled a Black Friday offer. | MEL Science US subscriptions |
| Sphero | No Black Friday 2026 offer shown on the first page of the catalog (24 of 184 products). | Sphero catalog |
LEGO says its US event will include discounts and gifts with purchase starting November 27, and that Insiders members get offers during the weekend before. Neither announcement establishes which sets will qualify or how much any particular set will cost. Products displayed on an event page are not necessarily discounted: when we checked on November 10, none of the sets shown there was marked down; the only reduced item was a storage product.
When we checked on November 10, KiwiCo’s coupons page advertised a promo code for new subscriptions, with its lowest per-crate price tied to an annual plan that renews automatically, and a separate first-month discount for email signup. The code’s terms gave an end date of November 16, so the page will have changed before Black Friday. Check the coupons page for the current amount, exclusions and eligibility, and read KiwiCo’s terms before choosing a subscription. We have not submitted an email address or tested a code at checkout. These checks cover the linked pages, not every retailer or country.
Build a STEM gift shortlist before comparing deals
Use these guides to choose the kind of activity first. They explain product fit and requirements; their inclusion here does not mean the products are on sale.
- Younger builders: Browse gifts for 6-year-olds, 7-year-olds and 8-year-olds, or compare take-apart toys for a child who enjoys assembly and rebuilding.
- Curious coders: Start with coding toys for kids and middle-school robotics kits. Check whether the recipient wants to build a robot or begin programming one that is already assembled.
- Older children and teens: Our guides for 12-year-olds and teens compare different project types. For a specific astronomy interest, see telescopes for teenagers.
- Adult hobbyists: Compare adult coding and engineering gifts with the recipient’s experience and available project time in mind.
- A specific project in mind: Compare science gifts for 10-year-olds, LEGO sets for 6-year-olds, computer-building kits or adult engineering kits. Use the exact product name when looking for an offer.
- A small budget or a late start: See STEM gifts under $25 for small picks and stocking stuffers, or last-minute STEM gifts if delivery time is short.
What makes an offer worth buying?
Match the exact model and bundle. Record the model or set number, included parts and seller before comparing prices. A smaller kit, older version or used item may cost less without being the same offer. Check the manufacturer’s age guidance and any adult-supervision requirements.
Check the total cost. Include shipping, batteries, tools and consumables. For a subscription, check the commitment, renewal price, cancellation process and whether the promotion covers only the first delivery. A low starting price does not tell you the cost of the whole gift.
Check software and delivery. Confirm that required apps work on a device the recipient can use, including permission to install software on a school computer. Read the seller’s delivery estimate and return terms for your address before ordering.
Compare the payable price. Look at the same model at other sellers and, where available, its price history. Check that an advertised promotion applies to your basket before paying. Choose the project you actually want; a large discount on the wrong kit is still money spent on the wrong gift.
