Our Guide to 2026 Sigma Shopping Policies
Where do I enter a Discount Code at Sigma?
Find the Discount Code box in the middle right of the Review Order Page on Sigma. Enter your Discount Code and click Apply to apply it to your order.
How do returns work at Sigma?
Sigma's return policy is fairly shopper-friendly, allowing refunds to the original payment method within 59 days and store credit or exchanges up to 90 days, which is generous compared to many beauty retailers. Used products can usually be returned unless abused, but sale items are final sale. Shoppers must cover return shipping and original shipping fees are not refunded. The 4-year warranty on brushes for manufacturing defects is a plus, though it only offers replacements, not refunds.
Sigma provides a flexible shipping policy with several delivery options, including standard and express shipping, making it convenient for shoppers who need their beauty products quickly. Free US shipping is available for orders over $65, which is a great perk for deal seekers. However, express shipping cannot be sent to PO boxes. Overall, Sigma's shipping policy is shopper-friendly, especially for those looking to save on larger orders.
Sigma's order cancellation policy is shopper-friendly, allowing you to cancel for a full refund if your order hasn't shipped yet. After your order has shipped, you are no longer able to cancel.
Sigma's Rewards program is a solid choice for frequent shoppers looking to save money and get extra perks. It's free to join and lets you earn points on every purchase, plus for actions like writing reviews or signing up. Points can be redeemed for discounts or free products, and members get birthday bonuses and early access to sales. Beauty pros and students can also benefit from a special PRO program with exclusive offers.
Sigma offers shoppers excellent opportunities to save during major sales events like Black Friday, Cyber Monday, and their Semi-Annual Sale, with site-wide discounts often between 20% and 75%. Shoppers can also enjoy perks such as free gifts and lower free shipping minimums, though some exclusions and restrictions apply. These sales are a smart time to stock up on beauty essentials.
Why might a Sigma promo code be ineligible at checkout?
Promotional codes cannot be combined with existing discounts or applied to specific product categories. You cannot use any coupon codes on sale items, Disney Collections, Value Sets, or Influencer Sets. Additionally, promo codes are invalid on any order where an automatic sitewide discount is already active on the items in your cart.
Excludes The Salon at Ulta Beauty, Ear Piercing, Skin Bar at Ulta Beauty and Benefit Brow Bar services, CHANEL, No1 DE CHANEL, Dyson, Early Black Friday Deals, Black Friday Deals, 5 for $5, 5 for $10, Beauty Deals, Beauty Steals, gift card purchases, or clearance.
