Athletes and Glasgow 2014 bosses cut the ribbon at the city's Central Station shop this morning.
Games officials said the store is creating new jobs as part of a drive which will see several hundred temporary posts created in the city to handle the sale of merchandise.
Ty Speer, Glasgow 2014 deputy chief executive, said: "Central Station is one of Glasgow's main commuter hubs with around 750,000 people passing through every week, making it the ideal place to showcase our range of Glasgow 2014 goods."
Weightlifter Peter Kirkbride, a Commonwealth Games Delhi 2010 silver medallist, was among those attending the launch of the retail outlet.
Michael Cavanagh, chairman of Commonwealth Games Scotland, said: "Team Scotland is anticipating massive levels of home support at the Glasgow 2014 Commonwealth Games. What better way for the whole of Scotland to get behind the team, show their support and play their part in the team's success than wearing our traditional team colours and bearing our distinctive logo."
