Find and test discount codes with ChatGPT agent mode
The poster uses ChatGPT's agent mode for multi-step research and testing of discount codes to get better prices before purchase.
Done withChatGPT Agent
- What they did
- The poster uses ChatGPT Work’s agent mode in a two-step workflow: first, they give it the exact product link, variant, quantity, and shipping destination so it can research public codes, sales, shipping thresholds, loyalty offers, rebates, cashback, competing retailers, and price-match options. Then, if browser access is available, they have it open the cart, try candidate codes one by one, record the discount and final total, reset the cart between tests, and pause for logins, CAPTCHAs, or other sensitive steps.
- How it went
- The claimed result is faster coupon checking and a comparison of which codes worked, failed, or gave the lowest final total. The post does not provide a concrete savings result, and it notes some sites block automation or require user takeover.
- Worth knowing
- The practical catch is setup: use the exact product page and cart, and explicitly tell it not to purchase; the image example suggests this can take about 60 seconds.
