My Auto Zone Rewards card is from 2007, hard to think that the card is close to 20 years old now. Last time I used it, I used it to scrape glue off the side of a truck LOL!
My Kroger card is 23 years old and is the same one I found in the parking lot of the Kroger near my dorm in college. Found it there and have used it since. The mag strip is long worn off and the barcode takes several tries to scan, but it works. I did take a scan of it about 7 or 8 years ago when it was more legible, so I may print that copy and laminate it for another 23 years lol.
