You know, Jenny from the song 867-5309 (see the above video if you weren’t around for the 80s). As parenting blog Parent Hacks points out, most stores can verify your membership by looking up your phone number. But it doesn’t have to be your number—just a number in the system, and people add fake numbers all the time to avoid giving out their own. Since 867-5309 is one of the most commonly remembered phone numbers, it’s almost always in the system. Punch in Jenny’s number instead of your own and you’ll get your discounts without handing over your personal information.
I love this trick so much. It makes me feel like a low level secret agent.
