It’s usually incidental. Costco’s receipts aren’t easy to get. You go to a particular page listing them all and then for each date you click view receipt and look for the thing you want. You can’t really search because the thing will be labeled SHWR103 or something.

I didn’t “use an agent to find a receipt” in the sense that I purpose built one. I just asked my existing agent that I talk to on telegram by photographing the thing I wanted to know if we could return and while I changed the baby it chugged along and by the time we were ready to go it could tell me whether we did buy it at Costco and when so I know if I can return it.
