## What it does
Keep a dated watch list of Costco purchases, check prices weekly, and draft the request. Costco states 30 days for costco.com orders.

## Who it's for
Costco members who buy electronics, appliances or other big items and want a simple way to catch a price drop after purchase. This is not financial advice. Do not paste your membership number or card details into a chatbot.

## Tools
- ChatGPT or Claude (free tier is fine)
- Your receipts or order emails for recent Costco purchases
- Five minutes a week to look up current prices

## Steps
1. Copy the item name, price paid, purchase date and where you bought it (warehouse or costco.com) from each receipt or order email. Leave out your membership number and card details.
2. Ask the chat for a table with each item's last day to ask. For a costco.com order, Costco's price match page states a 30-day window, so count purchase date plus 30 days. For a warehouse purchase it states no window, so ask at the Returns counter early.
3. Each week, look up the current price of every item still inside its window, in the warehouse or on costco.com, and tell the chat what you found. The chat cannot check live prices for you.
4. If a price is lower, ask the chat to draft the request. For a costco.com purchase, Costco's page points you to its price match request form. For a warehouse purchase, it says to inquire at the Returns counter at the warehouse where you bought the item. The page gives no eligibility rule for warehouse purchases, so the answer is up to the warehouse.
5. Log the request date. For costco.com requests, Costco says credits are typically issued within 5 to 10 business days to the original form of payment. If the window has passed, Costco's page says requests made after a promotion ends may be denied.

Help me track Costco price adjustments. Costco's price match policy for costco.com orders: for members other than resellers, a purchase that drops in price within 30 days of the purchase date is eligible. Items with specific sale dates also need the request inside the promotion dates. For warehouse purchases, the policy only says to ask at the Returns counter and states no window. Costco can deny a request.

My purchases: [item, price paid, purchase date, warehouse or costco.com]
Today's date: [DATE]

1. Make a table: item, price paid, last day to ask (30 days after purchase for costco.com orders; write "ask early" for warehouse purchases), weekly check date. Put the items closest to the deadline first.
2. When I give you a current price, say whether it is lower than what I paid, by how much, and whether the window is still open today.
3. If it is lower, draft the request. For costco.com: the details to put in the price match form. For a warehouse purchase: two sentences to say at the Returns counter.

Do not guess prices or dates. Ask me. Show me the table first. I send every request myself.

## Guardrails
- What it touches: Chat input you provide (ChatGPT or Claude (free tier is fine); Your receipts or order emails for recent Costco purchases).
- Needs your OK: Send, pay, publish, and account changes stay with you. Treat agent output as drafts first.
- Safety level: Drafts for you
- Asking after day 30 on a costco.com order. The window is counted from the purchase date, so set the reminder before the last day.
- Costco.com and warehouse purchases follow different routes: the online form versus the Returns counter.
- Items with specific sale dates need the request inside the promotion dates as well as the 30 days.

## Tips
- Check big-ticket items first, since the savings are largest there.
- Keep the receipt or order email with the log so the purchase date is easy to confirm.
- Costco's page says its price match does not cover other retailers' prices, and does not cover warehouse prices for costco.com purchases.
- Costco's page says precious metals are not eligible, and items with promotional limits are matched up to the limit quantity.

## Estimates (labeled, not measured)
- Time saved: About 10 minutes to set up, then about 5 minutes a week.
