Short answer: ThredUp has 7 working promo codes and deals in September 2026, and the best is worth up to 50% off. Sign up for the ThredUp email list for the largest first-order discount, then time bigger purchases to a holiday weekend rather than mid-month.

ThredUp discounts follow a rhythm. Once you know when the resale marketplace refreshes its promotions and which offers stack, you stop paying full price by accident. Here is the September 2026 picture.

How to apply a ThredUp discount code

The checkout flow at ThredUp puts the promo field on the payment step rather than in the cart, which is where most shoppers miss it. Copy your code first, then work through checkout normally and look for the discount box before you confirm payment. The total should change the moment the code is accepted — if it does not, the code has not applied, regardless of any confirmation message.

Why ThredUp codes fail

A rejected code almost always comes down to one of four things: it has expired, your cart is below the minimum spend, the code is restricted to new customers, or your basket contains excluded items. Clearance lines and gift cards are the usual culprits.

Clearance items are the most common exclusion. If a code fails, remove clearance lines and re-apply before assuming it is dead.
One promo code per order is the standard limit — but a code, sale pricing, a loyalty reward and a gift card are four separate layers that usually combine.
Gift cards, third-party marketplace sellers and pre-orders are excluded from sitewide codes at nearly every US retailer.

When ThredUp prices actually drop

Apparel markdowns run on a six-to-eight week cycle. New-season stock lands at full price, drops 20-30% around week five, and hits clearance once the following season arrives in store.

Codes are only one lever. At ThredUp, the combination that produces the lowest final price is usually a sale-priced item, a sitewide code applied on top, and free shipping claimed through a minimum-spend threshold you were going to cross anyway. Chasing a bigger percentage on a full-price item rarely beats that.

Getting more out of ThredUp long term

If you buy from ThredUp more than two or three times a year, the loyalty program and the email list are worth the inbox cost. Retailers reserve their deepest offers — early sale access, member-only percentages, birthday credit — for identified customers, and those offers are not published on coupon pages because they are tied to individual accounts.
