ONONDAGA COUNTY, N.Y. -- While many people are probably planning to ride out Sandy from the comfort of their homes, places like Wegmans and Lowe's tell us they plan to stay open to serve customers. And when it comes to getting ready for something like this, they say they're taking the advice we've heard so often during the past few days: Hope for the best, but prepare for the worst.

Customers are used to being able to rely on Wegmans John Glen store 24 hours a day, seven days a week. A company spokesperson says that won't change because of Sandy.

"We have an extensive emergency plan, but obviously our utmost concern would be the safety of our employees, the safety of our customers and also our food safety," said Evelyn Carter, Wegmans Director of Consumer Affairs.

Sandy's expected high winds are causing concerns of power outages. Wegmans says it has generators in all its stores that would keep lights and registers working, but customers’ best bets are the Taft Road store and John Glen store on Route. 57 in Liverpool.

Carter said, "Those two stores have the capacity to not only run lighting, but also refrigeration."

Power outages also aren't a concern for the Lowe's in Clay.

"We just filled our generator. We will be glowing like a Christmas tree," said Michael Russo, manager of the Lowe’s in Clay.

But even though the doors will be open to customers, managers are also prepared in case employees aren't able to leave.

Russo said, "We've gotten our contact information, emergency contact information for all our employees. We've even gone so far as having food back-ups in case my employees can't get back home."

Items like shopping carts and plants will also be secured in case of heavy winds. And both say this is nothing they haven't been through before.

Carter said, "We've been in this situation before. We've had storms in these areas before and we're glad to say Wegmans has fared well in these situations."

Both Wegmans and Lowe's say it would take a decision from their corporate or market offices to shut their doors. For now, these are two stores who say it will be business as usual during Sandy.
