Sigma Beauty runs several tiered discount codes based on how many items you buy, plus a range of sale categories and free gift deals. The featured voucher code offers 30% off when you buy 4 or more items, and it's the best value if you're planning a bigger haul and have a code to hand.
Buying just 2 items: Use the featured voucher code for 20% off, or check the "Buy 2 Products Get 15% Off" sale option if you don't have the code—the code saves you more. If you're looking at a specific bundle, the 30% off bundles sale might apply instead.
Buying 3 items: The featured voucher code for 25% off is your best bet here. There's no competing sale at this exact threshold, so the code wins out.
Buying 4 items: You reach the top tier of the featured voucher code and get 30% off, which is excellent value. Alternatively, the "Buy 4 Products Get 25% Off" sale gives 25% off with no code needed, so compare the two in your basket—the code saves you more.
Buying 6 or more items: The "Buy 6 or More Products Get 35% Off" sale kicks in and offers 35% off without needing a code. This beats the featured voucher code's 30% discount, so if you're buying six items or more, skip the code and take the automatic 35% off instead.
Shopping by category: Sigma Beauty runs specific category sales—20% off eye brushes and makeup, 20% off the bridal collection, 25% off the brush care edit, 20% off back to school essentials, and 15% off influencer sets. If these categories match what you need, check whether the category discount or your item count discount saves more at checkout.
Looking for deeper discounts: The "Up to 75% Off Selected Items" sale has the headline savings, but discounts vary by product. You may find better value here than on the code or quantity deals if the items you want are marked down heavily.
Orders over $50: You'll qualify for a free 3DHD Blender brush. At $150 and above, you get a free skincare brush set instead.
At checkout, you can only use one offer, so compare what you're buying against the available options in your basket and go with whichever produces the bigger saving. The code vouchers apply site-wide to any items you choose, while the sales are restricted to selected products, so check the terms on the Sigma Beauty website if you're unsure whether your selection qualifies.
