Aaron Davies, 30, from Sea Road, was sentenced to nine months in prison for 10 separate offences of breaching the Trade Mark Act 1994.
Chichester Magistrates’ Court ordered that the sentences run concurrently when Davies appeared before them on Friday (9 January).
In an entirely separate case, Davies was also sentenced to a further 66 months for firearms offences at the same hearing bringing his total prison sentence to 6 years and three months.
West Sussex Trading Standards launched a joint investigation into the counterfeit goods with Sussex Police.
Davies had been selling fake Beats headphones, Links of London watches, fake designer clothes and counterfeit Mulberry handbags over eBay. All these items were found at his Arundel business address on the Rudford Industrial Estate, Ford Road, Arundel, following a search by officers.
Lionel Barnard, West Sussex County Council’s Member for Residents’ Services with responsibility for Trading Standards, said: “This is good news for consumers and businesses.
“These criminal activities severely damage the local economy and legitimate traders by gaining a competitive advantage at their expense, and taking trade away from genuine hard-working businesses.
"We are extremely pleased with the outcome of this complex investigation. The case sends out a clear message that it’s unacceptable to defraud the public into parting with their money for goods that are anything other than genuine.“
