Quigley is currently back home enjoying a short holiday before he heads back to LA to begin training for his next professional bout.
But before he headed back stateside, the Ballybofey boxer popped in to wish both Michael and Neil all the best with their new business and good luck against the Dubs at Croke Park on Sunday.
While he was in the store, Quigley also checked out the custom-built golf section and tried out his golf swing on the northwest’s only golf simulator.
The Sky Sports news team also spent the morning in the shop interviewing Michael in advance of this weekend’s showdown with Dublin.
In advance of Sunday’s game, Michael Murphy Sports and Leisure is running a competition on its Facebook page inviting people to share pictures of their Donegal colours.
Some lovely images have been uploaded to date and the picture with the most likes will win its owner a pair of Dublin vs Donegal tickets for this weekend.
The winner will be announced on Friday at 4pm.
Since opening its doors, the shop has attracted thousands of customers and a whopping 11,600 likes on Facebook.
