Customers who rushed to a sale at Comet have expressed disappointment over the level of discount.
The electronics retailer had announced a "massive stock liquidation" ahead of store closures as early as next week, but angry shoppers took to Twitter to complain about the price reductions.
Scott Houston said: "Comet 'Firesale' is no more than 10-15% off. Prices aren't even competitive with online prices. Time wasted."
And Matt Arthur tweeted: "Anyone thinking of going to the Comet 'liquidation sale', don’t bother. 10% off audiovisual, 20% off kitchen appliances, still cheaper online."
Ajay Deshpande added: "If you are looking for cheap electrical goods then don't go to the Comet 'sale'!"
In response, a spokesman for administrator Deloitte said: "The discounts are gentle. It's not a hard sale."
The sell-off, which began at 9am on Thursday, is only available in its 236 stores, with customers unable to buy products online.
But some customers did manage to bag a bargain, with Alex Pegg tweeting: "In-pulse (sic) buy of the day, an Apple ProBook (£100 off from Comet)".
The electrical chain said gift vouchers would be accepted on sale items, following the temporary suspension of the tokens over the weekend.
But it warned customers it would not offer refunds, and any items ordered before the company went into administration that have not been paid for will not be delivered.
Comet's administrator Deloitte is in the process of winding down the business following its collapse on Friday, which leaves 6,600 jobs hanging in the balance.
But rival Dixons, which owns Currys and PC World, postponed hiring 3,000 Christmas staff by a week to allow Comet staff to apply.
It said it was "amazed" by the number of Comet employees that had enquired about positions so far.
Deloitte is attempting to find a buyer for the business and would not comment on speculation over store closures - although reports suggest stores could start to be closed next week.
If the chain does collapse, it will become one of the biggest high street casualties since Woolworths in 2008.
