Three would-be thieves attempted to break into Fredericks IGA in Jamberoo on Saturday, the night after the store celebrated its grand reopening.
Although nothing was taken - the alarm system apparently scared away the trio - the attempted break-in has left the store's owners Trevor Fredericks and his wife Carmel Goldsmith frustrated and disappointed.
It has been alleged the fire that destroyed the store in December 2012 was lit following a botched break-in.
Ms Goldsmith said there had been three attempted break-ins while the store occupied its temporary home while awaiting the reopening.
Armed robbers also held up the couple's other store at Kiama Downs twice in the same month as the fire.
"I just think that was very poor taste, and if people are going to do that they need to be held to account," she said.
"It's disappointing for the town too because we don't want that sort of thing happening in Jamberoo."
Lake Illawarra crime prevention officer Mark Scott said police had identified three suspects using CCTV footage, and one had been assisting police with inquiries.
Ms Goldsmith said people had come forward with suggestions on how to prevent future break-ins, including electrifying the fence.
