Some retailers are offering time for the most vulnerable customers during the coronavirus outbreak in the United States to shop around without the crowds.

Officials have said older adults and people with pre-existing health conditions are more susceptible to the new coronavirus, so several stores are dedicating time or opening earlier specifically for those customers.

Here's a full list of major retailers helping the elderly and vulnerable:

Albertsons: The company, which owns more than 2,200 stores nationwide like Acme, Vons, and Safeway has announced it will reserve time every Tuesday and Thursday from 7 to 9 a.m. for certain customers. Click here for a list of stores
