Tom Jordan, who runs two stores in Belfast, says: "Try as we might, we couldn't catch her out so we enlisted the help of a new company called Retailfraud.co.uk. The cameras cost £1,200 per shop and a week's monitoring was £140.
"Although we didn't get enough evidence for a prosecution, the company helped us make our systems so tight that the theft stopped completely. In effect, three weeks after the cameras went in they were paid for in what hadn't come out in the way of theft."
I am always happy to endorse individual companies that retailers recommend.
