Historical tracking confirms that 25% has held as the peak promotional discount across multiple months, making it a reliable benchmark for timing a purchase.

Sitewide Codes Reach 25% Off Across 37 Active Thirteen Thirtyone Offers
Thirteen Thirtyone's strongest sitewide discount currently reaches 25% off, drawn from a pool of 37 active, healthy coupon codes verified by SimplyCodes. This 25% ceiling is not a one-off spike. SimplyCodes historical tracking shows peak promotional discounts of 25% off recurring consistently across multiple months, which gives shoppers a dependable target rather than a fluctuating one.
For higher-priced pieces in the Thirteen Thirtyone catalog, a 25% sitewide code applied at full price materially changes the final total. Because the discount has held steady over time, there is little advantage to waiting for a deeper drop that SimplyCodes data does not show materializing. Browsing the full set of verified codes on SimplyCodes before ordering identifies which of the 37 is currently delivering the top rate.
A Single User-Submitted Single-Use Code Is Available for Thirteen Thirtyone
One single-use promo code for Thirteen Thirtyone sits in the SimplyCodes inventory, contributed by the shopper community. Single-use codes often unlock a discount that differs from the standard sitewide offers, so for a brand with a code pool as focused as Thirteen Thirtyone's, a single additional option is worth testing before settling on a public code.
Because only one such code exists at any given moment for Thirteen Thirtyone, availability is limited and worth checking at the point of purchase. Comparing its value against the current 25% sitewide ceiling determines which path produces the lower total on a given order.
Thirteen Thirtyone Collection Pages List Markdowns Like the $113 Misheard Shirt
Thirteen Thirtyone discounts select apparel directly on its official collection pages, with markdowns such as the "Misheard - 2Ways Shirt" reduced to $113 from a $323 regular price. These are product-level reductions set by the brand itself, separate from any code, and they appear on specific pieces rather than across the full catalog.
The markdown on the Misheard shirt represents a substantial cut off its standard price, the kind of reduction that typically outpaces a percentage-based code on an individual item. Checking the sale selections on thirteenthirtyone.com identifies which pieces carry these direct reductions, after which a shopper can compare whether the marked-down price or a 25% sitewide code applied to a full-price item produces the better result.
