Trade was brisk at the Glasgow 2014 superstore and at another outlet in Glasgow Central railway station at the weekend after stickers appeared announcing the sale.
The Games, which ended on Sunday August 3, were hailed as the best ever and saw Team Scotland win a record 53 medals.

Merchandise sales exceeded expectations, with as many as 46,000 Clyde mascots sold.
Around 76,000 T-shirts have also shifted in the past few months, along with 30,000 pin badges and 17,000 key rings.
But thousands more items have been sold as the shop prepares to close on Wednesday, creating space for Friday's parade through the city by Team Scotland's athletes, which ends in the square.
On hand to reap the benefits of the sale yesterday was Bobby Paterson, from Motherwell, North Lanarkshire. He said: "I've picked up about £400 worth of stuff there for around £140.
"Some of it is for family members living in Canada. My niece is coming over and she'll take some of the stuff back over with her to give to my mother's brother.
"He's too old now to travel himself but he just loves the city - he still has his Scotland flag up in the back garden. Hopefully, something like this will bring a little bit of cheer to him as well."
Alan Dunn, from Strathblane, Stirlingshire, added: "We were going to go through to the Edinburgh Festival but we came here to pick up a few things instead.
"I never got any tickets for the Games, even though I applied, but I've now got a good few keepsakes from the event."
A Glasgow 2014 spokesman said: "The Glasgow 2014 superstore in George Square has been a phenomenal success and with final stocks still flying off the shelves, it will now close on Wednesday rather than the end of August as originally planned.
"All of our ranges are selling very well across the stores from our Team Scotland merchandise through to our Scottish specific items. It has been brilliant to see crowds of supporters sporting the Glasgow 2014 brand."
Elsewhere, the Games organisers have established an online auction to sell off major memorabilia.
Among the items available is John Barrowman's opening ceremony 4x4, Usain Bolt's 4x400m relay baton, and a number of closing ceremony tents.
Nottingham-based website Leftover Solutions is also selling a number of Glasgow 2014 items, including swimming blocks, megaphones and rain ponchos.
