Thousands of packets of illegally-labelled cigarettes were discovered in a secret room in a shop in Corby town centre.
Trading standards executed a warrant at Kubus, in Corby, and a tobacco sniffer dog located the hidden void behind peg board in the basement of the store.
At Northampton Magistrates Court on Monday, July 29, Aram Baker Hassan pleaded guilty to having for supply 2,492 packets of cigarettes which did not have the required legal warnings on them.
He also admitted having 27 pouches of tobacco for supply which were not properly labelled.
Hassan was ordered to do 150 hours unpaid work and told to pay costs of £2,600.
An order was also made for the destruction of the tobacco seized.
A spokesman for Trading Standards said: “Anyone who is offered cheap tobacco or other types of illicit goods, or who sees them being supplied, should report it.”
The shop was visited by Trading Standards on October 3, last year.
All tobacco sold in the UK must have certain warnings in English and also a picture warning but none of the tobacco products found in the secret room complied with labelling requirements.
