A man jumped across a shop counter wielding a knife and stole more than £300 from the till.
The robbery happened at the Co-op store in Bloxham High Street at 7pm on Friday.
Shop manager Darren Bott said: "The man had already been acting strangely, trying to buy something then saying he didn't have the money for it.
"He was then seen hanging around in the store. We think he had been waiting for other customers to leave before approaching the counter and carrying out the robbery."
