Cobb County Commissioners will decide Tuesday whether to hold a referendum on primary day March 6 on whether to allow package sales of alcohol on Sundays.

If approved in March, the Sunday sales would begin June 1.

Three of Cobb six cities — Kennesaw, Smyrna and Acworth — are holding Sunday sales referenda on Tuesday. Like Cobb, Marietta plans to hold its referendum in March.

Cobb has no countywide elections on Tuesday, and a special election for Sunday sales would have cost $400,000, which Commission Chairman Tim Lee has said was not worth the expense.
