STAX discount codes and coupon codes in September 2026

From time to time, Stax will run free gift offers. Shoppers will be eligible to redeem the offer by hitting the minimum spending requirement, which changes according to the promotions. Among the gifts they have previously offered are socks, caps, and bags. The item will automatically be added to your order at checkout.

Stax will occasionally run a referral offer for a limited period of time. Previously, you could get a $20 discount for each friend you referred, provided that they made a successful purchase. All you needed to do was submit your name and email to receive all the necessary information. The discount you receive could be applied to your next purchase and is valid sitewide.

After comfy activewear? STAX is known for its best-selling leggings, seamless crop tops, and oversized tees. Get a discount code from this page and save while you stock up.

We gave it a go and here’s how it works:

1. Use a deal from this page.

2. Add leggings, sports bras, or loungewear to your cart.

3. On the checkout page, type your STAX discount code into the "Discount Code or gift card" box.

4. Apply it before paying to see your savings.

One suggestion: Always enter any discount codes at checkout before completing your purchase. Codes can't be applied retroactively once your order is confirmed, so double-check that you've added yours to avoid missing out on potential savings.

You can return items to STAX within 28 days of receiving them by starting a request through the Returns Portal. Options include an exchange, a refund, or 120% store credit. Return shipping costs $8.95, so consider whether store credit (with its extra value) works better for you.
