CircuitMess is running a 10% off DIY bundles promo code at the top of this page, and that code is best for shoppers buying selected DIY bundles who can enter a promo code at checkout. If you are buying one of the eligible DIY bundle products, the 10% off DIY bundles coupon at the top of this page is the quick way to take 10% off the item price. For other purchases, the site has a mix of bundle sales, subscription deals and a free gift offer that may save you more.
Big bundle purchases: when you plan to buy a named bundle such as the Wacky Collector's Bundle, Bestsellers Bundle, or Mars Exploration Bundle, use the listed sale that applies to that bundle. The Wacky Collector's Bundle has 26% off, the Bestsellers Bundle has 24% off and the Mars Exploration Bundle has 23% off, so these sale prices will usually beat a flat 10% code on the same bundles. The free gift included with any bundle purchase adds value to every bundle order while supplies last, so factor that in if the free gift is relevant to what you want.
Subscription plans and multi month purchases: pick the subscription-length deal that matches how long you want to commit. The 1 Month Wacky Robots Plan is offered at $37.99 per box and is the entry price for subscriptions. The 3 Months plan comes with $9 off, the 6 Months plan gives $30 off plus a Free Tools Pack, and the 1 Year plan gives $86 off plus a Free Tools Pack. For multi month subscriptions the fixed dollar off plus the tools pack generally saves more than a 10% code, because those offers apply to the specific subscription purchase.
Single kit or smaller purchase: if you are buying a single Wacky Genius or Wacky Master kit, check the item level sale first. Wacky Genius is 20% off and Wacky Master is 12% off; if the kit you want is on those sale prices they will usually save you more than the 10% DIY bundle code unless the code is valid on that exact SKU.
Buying selected DIY bundle items: the 10% off DIY bundles coupon at the top of this page is the correct choice when the product is one of the selected DIY bundles and you can apply a promo code at checkout. The code is website only and must be entered at checkout.
Our records show 10 sales and deals listed for CircuitMess in the 12 months to October 2026, and the biggest percentage sale in that period reached up to 40% off (August 2026). There are no recorded team checkout checks for CircuitMess in the 12 months to October 2026.
When you choose, compare the final totals and take whichever offer leaves the lower price. Use the 10% DIY bundles promo code only on eligible selected DIY bundles; for named bundle sale prices or subscription fixed dollar discounts, take the sale or subscription deal that applies to the product you are buying. If both a sale and a subscription deal apply and the terms are silent, treat them as separate choices and pick the one that gives the lower total.
