STAMFORD, Conn. (CBSNewYork) - It’s been three months since Sunday alcohol sales became legal in Connecticut and stores are reporting in.

WCBS 880′s Paul Murnane On The Story

Some stores complain they’re just doing six days of business over seven days now, but a group representing supermarkets told the Connecticut Hearst Newspapers that beer sales are up by double digits.

Carroll Hughes of the Connecticut Package Stores Association said it’s still early to gauge the impact.

“You could have a great day. You could have a great week. You could have a phenomenal 4th of July. You can have a great Memorial Day,” he told WCBS 880 reporter Paul Murnane. “And then Labor Day, a hurricane comes along or the weather is cold and rainy.”

But he said the cost of this is clear.

“We’ll probably, over an entire year, the package stores will probably invest somewhere between $6 and $9 million in extra cost,” he said.

Package stores have been allowed to also sell certain food items such as cheese, and a task force is examining other areas of state liquor law.
