How to Use a Temu Coupon Code on a Desktop Browser

Most Temu coupon instructions are written for the app, which leaves desktop shoppers hunting for a field that is genuinely tucked away. It exists, and once you know where it sits you will not lose it again.

Where the field actually is

Not on the cart page. Add your items, press checkout, and continue to the payment step where the order summary appears on the right. The promo or coupon entry sits inside that summary block, sometimes collapsed behind a small link you have to click to expand. Paste the code there and apply it before you choose a payment method.

Three things that break a valid code

Copying with a trailing space, which the field may not trim. Being signed out, since eligibility is tied to your account. And browser extensions that inject their own codes and overwrite yours — if a coupon extension is active, disable it for the checkout and try again.

Here are the current tested codes to paste into that field:

Confirm before you pay

The order total should visibly change and the discount should appear as its own line. If the code was accepted but the total did not move, the discount applied to nothing in your cart — usually a category exclusion rather than a broken code.

FAQ

Why can’t I find the promo field in my cart?

Because it is not there. It only appears once you reach the checkout payment step.

Do I need the app to use a coupon?

No, typed codes work fine on desktop. Only app-issued gifts and spin rewards require the app.
