The large distribution hub in Harlow in Essex has become the biggest Comet site so far to close, with 172 people losing jobs.
The closure comes among new warnings that all of Comet's stores are likely to shut by Christmas unless a last-minute buyer is found.
ITV News Consumer Editor Chris Choi reports from Harlow:
So far 40 Comet stores have closed, with seven more due to stop trading on Monday.
A further 118 closures are planned, with the remaining 70 stores likely to be shut by Christmas.
Many of those made redundant from Comet are angry.
Kirsty Chambers, a former employee of the Harlow distribution hub, said:
"I just feel that, again, I have to limit my Christmas for my child, she's only three years old and all the things that I've planned that I wanted to give her, I can't do that now."
The full list of store closures will mean a total loss of 3000 jobs since Comet went into administration after it ran out of cash.
Deloitte, Comet's administrator, said it was helping former staff, although full redundancy notices have not been available for all.
Lisa Dixs, another former employee at Harlow, said she wasn't satisfied with the insolvency firm's efforts to notify workers.
"It's not a good time of year to be losing your job really, but overall it's going to be hard.
"Thank you [Deloitte] for your non-help. They've not helped us at all and they've left us in the lurch" she said.
Comet previously held six percent of the British consumer electronics market, may mean gains for its rival Dixons, whose market share currently stands at 19.8 percent.
