At Stew Leonard’s in Norwalk, shoppers are in full snow-prep mode.

“To me, this is like a holiday—craziness from opening till close,” stated Nicole Weiss, vice president of Stew Leonard's Norwalk store.

Sales surged on Thursday ahead of Sunday's storm.

“We did 48% more than we did last year on that day,” Weiss told News 12, adding that she expects the increase to be 55%-60% Friday and Saturday.

“Everybody's coming over here right now,” said Maria Acevedo, who always does her weekly shopping on Fridays. On this one, she was joined by quite a few more people.

“Don’t want to be out on the roads, so just going to stay home and be warm and have plenty of food,” said Ben Soulliere, explaining the reasoning behind his trip. “If I’m stuck inside, I might as well enjoy it.”

Soulliere’s cart included milk, porchetta and apple cider donuts.

“Some meat, fish, and I'm making soup,” said Laura Fanzilli, as she checked out.

But customers aren't the only ones getting ready. The store has also rolled out a plan. It began with shifting staff's schedules.

“We have 20 extra cashiers probably on the schedule today—Friday—and Saturday,” Weiss explained. “And we've also added extra bakers to the schedule to extend their shifts.”

Production is amped up for things like bagels and prepared foods, to make sure there’s plenty for the expected extra shoppers.

Stew's also took precautions with the items that are always top sellers before a storm. “We've ordered extra milk, eggs, bread,” said Weiss.

Sales of those items are expected to double the day before the storm. Winter essentials are also in demand.

“We've brought in extra trucks of ice melt between all our stores. Ice melt is up 40%,” Weiss told News 12. “We have shovels. We have sleds. I’ve never seen in the past probably ten years so many people buying sleds. We always have extra that we pack away in the winter. We will sell out of sleds this weekend.”

It's not just food and winter supplies that people are grabbing. Stew Leonard's Wine & Spirits reports sales of red wine and bourbon are expected to jump 20% before the storm.
