OuterKnown Promo Codes & Coupons September 2025

OuterKnown offers multiple savings opportunities beyond standard promotions, with our data revealing several insider strategies that can yield discounts of up to 70% off retail prices. SimplyCodes research has identified the most effective money-saving tactics based on historical promotion patterns and community-verified deals.

Shop the "Final Sale" Section for Maximum Discounts

OuterKnown's "Final Sale" section consistently offers deeper discounts than their regular sale section. According to SimplyCodes shopping research, items in this section are typically marked down 40-60% off original prices, compared to the 20-30% discounts found in the standard sale section.

These Final Sale items are fully clearanced and will not be restocked. Our analysis shows that OuterKnown regularly adds new inventory to this section when transitioning between seasonal collections, making it an excellent opportunity to find quality sustainable apparel at significant markdowns.

To maximize savings, check the Final Sale section before browsing regular sales. Sort by your size first, as inventory in this section is limited and not available in all size ranges.

Plan for the Annual Warehouse Sale Event

OuterKnown hosts a major warehouse sale each year in early May in Tustin, California with discounts up to 70% off retail prices. SimplyCodes community members who attended previous events reported finding core items like jeans, t-shirts, and swimwear at their lowest prices of the year.

The warehouse sale features both current and past-season merchandise. Our research indicates that basics and signature items like their S.E.A. jeans are typically included, though selection varies by size and style.

Mark your calendar for early May and follow OuterKnown's social media for exact dates and location details. If you're near Southern California, this in-person event offers the deepest discounts available on OuterKnown merchandise throughout the year.

Subscribe to the Newsletter for Early Sale Access

OuterKnown gives newsletter subscribers early access to their Semi-Annual Sales. According to SimplyCodes analysis of previous promotions, subscribers typically receive access 24-48 hours before sales open to the general public.

Early access provides a significant advantage for securing popular sizes and styles. Our community reports that high-demand items in common sizes often sell out during the early access period before the public sale even begins.

Sign up for OuterKnown's newsletter through their official website to receive early sale notifications. Be sure to check your email regularly during key sale periods (typically mid-December and mid-June) to take advantage of this head start.

Utilize Single-Use Promo Codes

OuterKnown has 364 single-use codes available through the SimplyCodes community. Our verification system tracks these codes, which are typically unique one-time use codes that may have been shared from email promotions or loyalty offers.

Single-use codes can offer exclusive discounts not available through public promotions. While individual code success rates vary, SimplyCodes data shows that trying multiple codes increases your chances of finding a working discount.

Check the SimplyCodes browser extension before completing your purchase to try available single-use codes. The extension will automatically test codes to find working discounts without requiring manual entry of each code.

Consider Similar Sustainable Brands

OuterKnown has 1,416 competitor codes from similar sustainable apparel brands. SimplyCodes research indicates that many shoppers interested in OuterKnown's sustainable practices also shop at brands with similar ethical commitments and aesthetic styles.

Competitor brands often run promotions during different time periods. Our shopping analysis shows that checking alternatives when OuterKnown isn't running major sales can yield better immediate savings while still supporting sustainable fashion.

Browse competitor codes on SimplyCodes to find alternative sustainable brands with active discounts. This strategy is particularly effective if you're flexible about which brand to purchase from and prioritize both sustainability and savings.

Take Advantage of Free Shipping and Returns

OuterKnown offers free standard shipping on all domestic orders with no minimum purchase requirement. According to our assessment of their official store policy, this benefit applies year-round and is not limited to promotional periods.

The brand also provides free returns on regular-priced merchandise. SimplyCodes verification of OuterKnown's return policy confirms that customers can return non-Final Sale items within 30 days of purchase without paying return shipping fees.

Consider these built-in benefits when comparing prices across retailers. When factoring in the value of free shipping and returns (typically $5-15 per order), OuterKnown's pricing may be more competitive than retailers charging these fees, even if their sticker prices appear lower.
