Watch prices after you buy

The bot watches prices on things you buy often or plan to buy, and alerts you to drops.

Starting prompt (adapted)

Keep a watchlist of items I plan to buy and items I bought in the last month. Alert me when a price drops and tell me whether a recent purchase is still within its return or price-adjustment window. Do not buy, return, or cancel anything without my approval, and keep a list of each return deadline for me.

Written for this site from what the cases below did. It is a starting point, not a prompt anyone posted. Fill in the parts in brackets.

What you still do

  • Add items to the watchlist
  • Approve any purchase, return, or refund claim

Where it tends to fail

  • No post gives an amount saved
  • Tracking prices saves nothing until you buy at the lower price
  • One post promotes a tool its author is building

How well it's backed up

The posts are text only. One says the bot already paid for itself with no figure, one is a parts list tracked before a sale, and one comes from someone building the tool as a product.

Text only: 3.
