It was an enjoyable read and a light break from some of the heavier reading I've been into lately. My only recommendation to the author would be to consider removing the introduction as it was far too explanatory of the plot. It wasn't needed as the plot unraveled very well during the telling of the story.
If you like quirky, British humor, this would be an excellent Sunday afternoon read. I feel Michael Wilton has an interesting style and I look forward to the next work to spring from his pen. Judging from his Amazon page his work to date has been Children's Books, so it was interesting to see him handle an adult story like Save Our Shop. A simple, unpretentious, comedy of manners that earns Save Our Shop four stars.
