The woman known on Facebook as Laura Jean posts “RUN!!!!” — and more than 109,000 followers listen. A reading specialist at a west suburban elementary school by day, Laura Benning started the group in 2017 to share coupons and sales with her friends. She still does that: If you want to find a Bubba insulated tumbler for $6 (regular price: $15), you’ve come to the right place. But when toilet paper started disappearing from stores, her shrewd eye suddenly became indispensable. Benning began hunting down essentials and sounding the call when hard-to-find COVID-19 survival gear such as Clorox wipes, hand sanitizer, and trampolines (desperate parents take desperate measures) were, deal or not, fleetingly back in stock.
