Sigma Beauty is showing a 30% off code when you buy 4 or more items, and that is the lead offer on this page. The 30% off code at the top of this page is best if you plan to buy four items and want the simplicity of a single code at checkout. For larger multi item hauls there are public sale deals that can save more, and category sales that include freebies on qualifying minimum spends.
-
Buying one item or a small add on: if you only want a single product, none of the buy multiple item codes apply. Look for the site sale prices instead, including the summer sale and up to 50% off selected products, which may give a bigger saving on that one item than any code. If you are a first time subscriber, the newsletter signup can be worthwhile for future offers but it is not a checkout discount and does not save on this single item.
-
Buying two items: use the 20% off code that requires a minimum of 2 items. For a $60 order made of two $30 items, the 20% code takes 20% off, leaving $48, a saving of $12. The site also runs a sale that gives 15% off for two items but 20% from the code saves more in this case.
-
Buying three items: use the 25% off code that requires 3 items. For example, on a $90 order (three $30 items), the 25% code reduces the total to $67.50, saving $22.50. The 30% code needs 4 items so it is not eligible for three item purchases.
-
Buying four items: the 30% off code at the top applies once you have four items. For a $80 order made of four $20 items, the 30% code reduces the total to $56, saving $24. A public sale also offers buy 4 get 25% off, but the 30% code still saves more on a four item cart.
-
Buying six or more items: the site sale that gives 35% off for six or more items (no code required) beats the 30% code. For six items at $20 each ($120), the 35% sale reduces the total to $78, saving $42, versus $84 and $36 saved if the 30% code were allowed (it is not, because the sale needs no code). Use the 35% sale when you reach six items.
-
Category sales and freebies: face brushes and face makeup get 20% off and orders over $50 receive a free 3DHD Blender. For example, a $55 face brush order after 20% off becomes $44 and also qualifies for the free blender. A free skincare brush set comes with orders over $150, so factor that into big carts.
Our records show 38 offers listed for the brand in the 12 months to October 2026 (37 sales and deals, 1 code). Percentage codes have been rare in that window, with only one percent code recorded and the biggest code in that period being 15% off. Our team performed 1 checkout test of a Sigma Beauty offer in the 12 months to October 2026 and kept a screenshot as proof.
To choose, compare the total cost after each eligible discount and take the lowest final price. No offer here says you can stack these codes with the site sale rates, so treat code and no code deals as alternatives and pick the one that leaves you with the lower total.
