The Sunday Standard's promo codes cluster around a baseline 10% storewide discount, with SimplyCodes tracking 6 healthy codes and a single community-donated single-use code currently active. Historical tracking across two years shows discounts rarely exceed that baseline, with one notable exception: September markdowns have reached 20% off. The merchant splits across two storefronts with different free-shipping thresholds ($175 general retail, $100 skincare), and certain curated lines like RŌZ clean haircare are excluded from promotions entirely.
September Marks the Peak Discount Window, With 10% Off as the Year-Round Baseline
The best discount recorded at The Sunday Standard over two years of tracking is 20% off, appearing in September, while the reliable year-round maximum sits at 10% off storewide. SimplyCodes data currently shows 6 healthy codes available, all in the 10% range, giving most orders a dependable baseline saving regardless of timing. For purchases that can wait, holding out for the September window has historically delivered double the standard discount. For everything else, applying an active 10% storewide code through SimplyCodes captures the baseline value without waiting on a seasonal spike.
A Community Single-Use Code Offers a Backup When Public Codes Fail
One active single-use code submitted by the SimplyCodes community is currently available for The Sunday Standard, and it matters most when the public 10% storewide codes reject your specific cart. Because the merchant carries curated third-party lines with their own pricing rules, public codes occasionally fail on carts containing restricted items. Checking the community-donated code on SimplyCodes gives you a second redemption path before paying full price. Given that only one such code is live, it is worth verifying before checkout rather than assuming the standard storewide offer will apply.
Match Your Free Shipping Threshold to the Correct Storefront
The Sunday Standard runs two separate storefronts with two different free-shipping thresholds, and ordering from the wrong one can cost you unnecessary delivery fees on a skincare purchase. The dedicated skincare storefront at sunday-standard.com ships free on orders of $100 or more, while the general retail shop at shopthesundaystandard.com requires $175 or more. Because skincare routines often span multiple products, consolidating your regimen on the skincare storefront reaches free shipping at a lower cart total than the general shop. Shoppers local to Chicago can skip shipping entirely by selecting in-store pickup at the West Armitage Avenue location, with orders ready within 24 hours.
RŌZ Clean Haircare and Other Curated Lines Are Excluded From Promotions
RŌZ clean haircare products at The Sunday Standard are strictly excluded from sales and promotional events, meaning no storewide code will discount them at checkout. According to The Sunday Standard's official product policies, certain curated clean beauty brands carry firm pricing exclusions that override sitewide offers. When a 10% storewide code fails to apply, the most common cause is an excluded item sitting in the cart. Separating RŌZ products into their own order lets any eligible items still receive the discount rather than blocking the code across the entire purchase.
