The AlloyWorks 10% off promo code at the top of this page is the lead offer, and it is best for most orders that are not already on a marked down item. The code takes 10% off your entire order across the listed product ranges, so it suits single purchases and multi item carts where no higher sale price applies. It cannot be combined with other promotions.
Small orders under $50. If this is your first order and the cart total is low, use the $5 off first order code. On a $40 order, for example, the $5 off code brings the total to $35, while the 10% code would leave $36. You save more with the $5 off when your pre discount total is less than $50.
Typical single item purchases from $50 to any higher total. Use the 10% off promo code above. For a $200 radiator not in the summer sale, the 10% code reduces the price to $180, a $20 saving. That will usually beat the lower percentage codes (6% and 5%) and the fixed $5 saving once the order is $50 or more.
Buying two or more products. There is a specific extra 6% off code that requires two or more products. It still cannot be combined with other promotions, so compare it to the 10% code. For a two item cart totaling $300, the 10% code leaves $270, a $30 saving, while the extra 6% code leaves $282, an $18 saving. The 10% code is the better choice unless your two item total is small enough that the $5 first order credit still wins.
When items are in the summer sale. Sale prices are selected items marked down by up to 50%. If the product you want is already reduced, the sale price can beat any percentage code. For example, a radiator marked down 50% from $200 to $100 is cheaper than applying the 10% promo to the full price. Use the sale price on selected products; percentage codes cannot be stacked with sale promotions when terms forbid combining.
Low percentage alternatives. There are several 6% and 5% promo codes on the page. These are only useful when the 10% code is not accepted for your cart or when a specific code requirement makes one eligible and the 10% ineligible. In every case where both apply, the 10% code gives the larger saving.
Our records put this 10% lead code above the typical code for AlloyWorks. In the 12 months to October 2026 we listed 32 offers for the brand (17 codes and 15 sales). The biggest percentage code in that period was 20% off and the typical percentage code was 8% off. Our team carried out 17 checkout tests in the 12 months to October 2026.
When you choose, work out the final totals and take whichever offer leaves the lower price. Many of the promo codes here state they cannot be combined with other promotions, so do not expect to stack them; pick the single code or the sale price that gives the lowest final amount.
