Bare shelves at the grocery store was an all-too-common sight at the height of the pandemic, and once again many shoppers are searching for some of their go-to items.

Retail analyst Marshal Cohen says a supply chain shortage is the cause of all the problems. He says there simply aren't enough workers to move items across the country from areas like California.

"We have more goods that we need that are sitting either assembled or ready for assembly sitting on these cargo ships," says Cohen. "And there's just not enough truckers to transport them out, not enough rail cars and laborers to get them onto the rail cars."

At the Walmart in Westbury, items like meat, juice boxes and some frozen foods are hard to come by.

That's causing some shoppers to buy certain items in bulk.

Other shoppers aren’t as concerned.

“There’s plenty of stuff on the shelves, I wouldn’t panic,” says Garden City Park resident Toni Zabicki.

A spokesperson for Stop & Shop says they're in close contact with suppliers to keep high demand products on the shelves.

Some experts say eventually it may be hard to find specific brands.

Experts predict the problem could last at least through the end of the month.
