Sometimes the software side of the newsagency channel can get pretty dirty. I saw this happen last week when a salesman claimed that his system had certain features that others did not have. He lied. At least two other systems have all the features he claimed only his system had. The newsagent went with his system solely because of the claim. They will learn the consequences for not checking if they were being told the truth.
One reason software companies lose market share is that lies like ones told last week come back and bite them.
Newsagents considering installing software should shop around. The software marketplace is going through a shake up. Check sales claims. Trust only what is proven.
