Discount retailer Poundstretcher has been fined £65,000 for breaching health and safety regulations at a Lincolnshire warehouse.
Conditions at the warehouse in Stamford were a "disaster waiting to happen", Lincoln Crown Court was told.
An environmental health inspector found poor lighting, trip hazards and a risk of stock falling from height.
The firm, which pleaded guilty, was prosecuted for similar breaches at the same premises in 2011, the court heard.
The latest problems were spotted on a visit to the warehouse on 6 June last year that was prompted by an employee raising concerns.
'Obvious risks'
At the time, the store manager admitted overstocking was a problem but she did not have the power to refuse deliveries.
Court recorder Stephen Lowne said said it was a "miracle" no member of staff had either been hit or submerged by stock at the warehouse.
"The risks were so obvious it was astonishing it was allowed to get to this stage," he said.
"It is a disaster waiting to happen."
Poundstretcher Ltd admitted two contraventions of health and safety regulations and one breach of duty to employees.
It said it had since made changes to procedures.
As well as the £65,000 fine, the company was ordered to pay almost £14,000 in costs.
