December isn’t the first month people think of for St John Knits sales, but that’s exactly why the best codes slip through the cracks. You’d expect end-of-year clearance to start after Christmas, not before, so retailers keep prices steady through the first two weeks. That means December promo codes are often smaller, quieter, and targeted at specific styles rather than sitewide fire sales. They’re easy to miss if you’re scrolling past the big flash-sale banners or waiting for the Boxing Day markdowns. Don’t wait for January when the same sweater you want now might cost you 10 percent more.
Why December discounts feel different
The conventional wisdom says winter apparel discounts don’t start until after the holidays, and in most years that’s true for outerwear and heavy coats. St John Knits, though, operates on a different calendar. Their classic merino wool twinsets and cashmere wraps sell year-round, so December becomes a soft spot: inventory needs to clear before the next season’s deliveries arrive in January, but fashion editors haven’t started screaming about “must-have holiday gifts” yet. That creates a narrow window where promo codes can apply to full-price items without the site screaming “SALE” in neon pink. The discounts look small—often 10 to 15 percent—but they stack on top of the built-in quality of a St John piece that holds its shape and color for years.
Where the standard advice still works
If you’re hunting for a specific St John item—say, the signature ribbed turtleneck in oatmeal—patience is still your best ally. The site rotates new promo codes every Tuesday, timed to match the weekly newsletter drop, and the best ones appear for items that have been sitting in the warehouse for more than 45 days. That’s the moment when inventory managers start nudging marketing to clear the rack without devaluing the brand. In December 2018, that meant codes like STJOHN15 or HOLIDAY10 popped up for older styles like the classic striped crewneck in sizes XL and up, where demand drops after the first frost. The discount wasn’t flashy, but it applied to a sweater that still retailed for $295, so the dollar savings mattered.
What the holiday noise gets wrong
Everyone talks about Black Friday and Cyber Monday, but St John Knits rarely plays that game the way fast-fashion sites do. Their December promos are more likely to show up in abandoned-cart emails sent on a Thursday night than in a site-wide banner. The codes are often single-use, tied to your account, and hidden behind a “holiday gift guide” pop-up that disappears if you click away. That means the standard advice—“check the footer, check the newsletter”—isn’t enough. You also need to scroll past the first three product rows on the homepage, where St John showcases new arrivals, and look at the bottom of category pages where older inventory gets pushed. In December 2018, shoppers who did that found a code labeled DECEMBER10 tucked under the “gift ideas under $200” section, valid only for orders over $150. It wasn’t advertised on social media, but it worked.
When flash sales backfire
St John Knits runs limited-time flash sales that can feel like a bargain, but the discounts are usually shallow—8 percent off a sweater that’s already been marked down twice. The bigger risk is inventory exhaustion: the styles disappear within hours, and the code stops working before you can check out. In December 2018, a flash sale on cashmere cardigans claimed “20 percent off, today only,” but the XL and XXL sizes vanished inside 90 minutes, leaving only the smallest sizes for the remaining shoppers. That’s fine if you wear a small, but frustrating if you need a gift in a hurry. The promo codes that survive the holiday rush are the ones tied to newsletter signups or loyalty tiers, not the ones screaming “limited time” in 72-point font.
How to actually decide
- Check the St John Knits homepage on a Tuesday morning—new promo codes often drop then.
- Open the weekly email and scroll to the bottom of the message for single-use codes.
- Look at category pages for older styles; the discounts are usually listed in the fine print.
- If you see a flash sale, verify stock for your size before you commit.
- Combine promo codes with gift-card purchases for layered savings.
Don’t assume December is a dead zone for St John Knits deals. The codes are smaller, quieter, and easier to miss, but they can still cut 10 to 15 percent off items that would cost more in January. Focus on older inventory, check your email, and ignore the screaming banners—those are usually for someone else’s holiday rush.
Do December St John Knits codes really expire after Christmas?
Not always. Some codes stretch into early January, especially for items that didn’t move during the holidays. Others vanish on December 31, but only for new customers—returning shoppers sometimes get an extra week.
Can I stack a promo code with a gift card?
Yes. St John allows promo codes to apply on top of gift-card balances, so you can use a $50 gift card and a 10 percent code on the same order. Just make sure the final total covers the minimum spend for the code.
| Step | What to do | Where to look |

| 2 | Scan category pages | Look for older styles with fine-print discounts |

| 5 | Combine codes | Pair promo codes with gift-card balances |
If you’re hunting for St John Knits deals this December, forget the hype around Black Friday and Cyber Monday. The real savings hide in the quiet corners—newsletter footers, old inventory pages, and single-use codes tucked behind “gift ideas.” Those discounts may look small, but they apply to items that rarely drop below full price, so they’re worth the extra scroll. Ignore the noise and chase the quiet codes; they’re the ones that still work after the holiday rush fades.
