CircuitMess is running several ways to save right now. The 10% off code for DIY bundles is the headline promo and works well for makers building specific kits, though the deeper discounts below may work out better depending on what you're buying.
Buying individual items or kits: if you're after a specific product rather than a full bundle, check whether it falls under the sale discounts. The Wacky Master is on sale at 12% off, the Wacky Genius cuts deeper at 20% off, and selected products across the site go up to 29% off. On a smaller single item purchase, one of these percentage reductions will likely beat the 10% bundle code.
Shopping for the featured bundles: CircuitMess has four named bundles on sale. The Wacky Collector's Bundle gives you 26% off, the Bestsellers Bundle runs 24% off, and the Mars Exploration Bundle offers 23% off. Compare these discounts against the DIY bundles code (which gives 10% off) and pick whichever percentage is higher. Since these are fixed dollar bundles, the highest percentage discount on the bundle you want will always save you the most.
Choosing a Wacky Robots subscription: if you're committing to a monthly box, your saving grows with the length of your plan. The 3 Months plan comes with $9 off, the 6 Months plan steps up to $30 off plus a free tools pack, and the 1 Year plan is the strongest value at $86 off plus a free tools pack. The 1 Month option at $37.99 per box is the entry point if you're testing the service. For longer subscriptions, the per box saving is better, so compare how many months you're willing to commit against the total discount.
Bundle purchases with added value: every bundle order qualifies for a free gift included with the purchase, which sweetens any of the bundle deals above.
Special reservations: if you're interested in the Makerphone 2.0, CircuitMess is taking reservations at just $1 through September 11, 2026. This is a low cost way to secure one before full launch pricing kicks in.
At checkout, only one offer applies to your order, so compare what you're buying against the available discounts and take whichever saves the most money. The percentage deals on specific bundles and products often outpace the 10% code, but work out the exact numbers for your cart to be sure.
