ARMED robbers raided a Kiveton store on Wednesday morning, threatening staff with a knife and a gun.
Police are now searching for the culprits and appealing for any information about the attack.
Three men entered the Costcutter shop on Station Road on Wednesday 2nd January at around 7.45am.
It is thought one man was holding a knife, and another had a gun - possibly a rifle.
All three had their hoods up and their faces covered as they threatened shop workers in the terrifying ordeal.
They made off with cash, alcohol and cigarettes in a getaway vehicle which could have been a large dark-coloured car, possibly a Vauxhall Vectra with an 03 registration.
No-one was hurt in the incident.
Shop owner Irfan Ghani has told the Dinnington Guardian he will offer a £1,000 reward to anyone who provides information leading to a conviction.
All three men are described as being of thin build and in their late teens to early 20s.
They all varied in height. One was around 6ft 2ins, the second around 5ft 8ins and the third about 5ft 4ins tall.
Police believe they may have been loitering near the railway bridge on Station Road just before the incident.
They are urging anyone with information to come forward if they saw the robbery, the men near the bridge or the vehicle before or after the robbery.
Call South Yorkshire Police on 101, or Crimestoppers anonymously on 0800 555111, quoting incident number 130 of 2nd January 2013.
