That’s how often grocery prices can change in a single day at some stores. One blink and your eggs are cheaper. Or not. Welcome to grocery aisle gladiator match, where price tags refresh more than your Instagram feed, thanks to electronic shelf labels (ESLs) (paywall link). 

📢 Check for recalls: The U.S. Consumer Product Safety Commission site is worth checking now and then. You can search by categories, filter by date or hazard and sometimes get a refund or replacement. And if there’s ever a big recall, don’t worry, I’ll warn you here in my newsletter, too.
