What the source did
- He posted it as a reply under a widely shared post of Costco shopping tips. It drew 51 likes and 36 bookmarks within a day.
- After a Costco run he uploads the receipt to his Grok Bot.
- He tells it to check each week, for 30 days, whether any item on the receipt has dropped in price.
- At day 28 it reminds him which items qualify, so he can get the difference back before the 30-day window he works to runs out.
- He says it usually pays for itself each month. He gave no dollar figure.
- In a follow-up reply he shared the bot as a free template, Receipt Price-Drop Checker.
- Heads-up: another account posted the same tip word for word later that day; this recipe credits @dig_ggy, who posted first and published the template. Check Costco's current price adjustment terms at your warehouse; the post doesn't spell them out.

Our notes
- What it takes
- His free Receipt Price-Drop Checker Grok Bot template and a photo of each Costco receipt. He shared no prompt text beyond the post; the template does the weekly checks.
- Where it breaks
- Receipts you forget to upload, online prices that differ from your warehouse, and claiming after the window closes (his reminder comes at day 28 of 30).
- Human checkpoint
- The bot only checks and reminds. You decide which items to claim and ask Costco for the adjustment yourself.
- Tools involved
- Grok Bot, His Receipt Price-Drop Checker template (free), Photos or uploads of your Costco receipts

Get their template
Made and published by DIG. Start here; it is their original, not ours.
Our adapted version
Ours Our version, built from his post. His own template is linked above; use that first. Fill in the [BRACKETS].
Track my Costco receipts for price drops. Don't contact anyone.
1. When I upload a receipt, list every item with its item number, price paid and purchase date. Save it.
2. Once a week for 30 days after each purchase, check the current Costco price for each item.
3. If an item is now cheaper, note the new price and how much I'd get back.
4. On day 28 after each receipt, send me one reminder: the items that dropped, the difference for each, the total, and the receipt date to bring.
5. If nothing dropped, just say so on day 28.
Only report and remind. Never contact Costco, start a return, buy anything or use my payment details.
Approval rule
🛡
The bot only checks prices and reminds you. You decide which items to claim and ask Costco for the adjustment yourself; it never contacts the store, returns, buys or pays. Sending, buying, posting, and deleting always need a human.
Set it up
- Add his Receipt Price-Drop Checker template from the link above.
- After each Costco trip, snap or upload the receipt.
- Let it check weekly; you don't need to do anything until the reminder.
- On day 28, read the list of items that dropped.
- Ask Costco for the price adjustment on the items you want, with your receipt, before the window closes.
Common failures
⚠
- Waiting past the window. His reminder comes at day 28 for a 30-day window, so there's time to act.
- Forgetting to upload. It can only track receipts you give it.
- Online prices that don't match your warehouse. Confirm the lower price before you ask.
Variations
- Use it for other stores. His template is written for any receipt with a price adjustment window, not only Costco.
