The supermarket underwent a major refurbishment last year, with the new layout aimed to make it easier for customers to shop.
Police said the break-in didn't appear to be linked with the two armed robberies that have happened in Yate in the past 24 hours, with a firearm being sighted in one.
Anyone who saw what happened, or can assist with the investigation, is asked to call 101 and give the call-handler reference 5221027464.
