I was also invited to a focus group there about 2 years ago, and the manager then told me they had them every month or so, but quite frankly I felt that (a) if they NEED to be told at a focus group to clean their store and make the tills match up to what the shelves say, when there was a queue of people at Customer desk telling them these things, then they're not worth my time, and (b) my time is precious and they aren't paying me so I ain't telling them!
