What they did
A pharmacy automation analyst suggests giving Grok Bot your Costco receipt and asking it to tell you when anything you bought goes on sale within 30 days, so you can ask for a price adjustment instead of paying full price.
How it went
An alert with the item and the amount you can claim back.
Worth knowing
- A tip, not a reported result. Check Costco's current price adjustment rules for your country and store (some items are excluded), and note that online and warehouse prices can differ.
Prompt
Cleaned version rewritten from the source — not a direct quote.
Here is my Costco receipt from [date]. Check the current price of each item at [my warehouse / costco.com] every few days until [date + 30 days]. If anything is cheaper than I paid, tell me the item, the difference, and what I need to bring to claim a price adjustment.
