Starting Sunday, liquor stores in Massachusetts will be allowed to open two hours earlier, at 10 a.m. The change is significant for some stores but not all says Frank Anzalloti of the Massachusetts Package Store Association.

“Stores along the New Hampshire border, I suspect, will welcome the extra hours to compete with a state where Sunday sales begin earlier,” he says.

But Anzalloti says stores within the interior of of Massachusetts may not choose to apply for a license to add the extra hours.

For Ryan and Casey liquor store owner Christy Faufaw in Greenfield, Mass., time will tell if sales in the two extra morning hours can cover the cost of labor, as the state requires workers be paid time and a half on Sundays.  Her store will open this Sunday morning at 10.  But Faufaw says she loses more customers because of Massachusetts’ taxes than she does because of Sunday hours.

“We have such huge excise taxes on alcohol compared to some of the neighboring states,” Faufaw says.

Hours vary from state to state around the country. In New Hampshire, liquor stores are all run by the state and can open as early as 8 a.m.. In Connecticut, stores open at 10 a.m. In Vermont they open at 6 a.m.,  seven days a week.
