# Find and Test Coupon Codes Automatically

## Try Every Sofa Coupon

Browser Use tries each code at the real checkout and reports the one that saves the most.

![Try Every Sofa Coupon - the target site](https://browser-use.com/_next/image?url=%2Fshowcase%2Fmore%2Fsofa-coupon.png&w=3840&q=75)

## The prompt

I'm buying \[sofa\] from \[store\]. Find every coupon code you can, try each one at checkout, and tell me which saves the most. Stop before paying.

CopySwap the \[bracketed\] parts for your own before running.

Runs on [stealth browsers](https://browser-use.com/stealth-browsers) at $0.02/hour. No card required · [pricing](https://browser-use.com/pricing)

## Why it's hard

Coupon sites list fifty codes and roughly three of them work on the thing you are buying.

-   Codes that validate but silently apply nothing
-   Exclusions that only surface at the payment step
-   Stacking rules where the best single code beats two
