As mentioned before, depends whether they give you a time restriction on your parking on their car park .. some supermarkets do charge town shoppers for long stay.
I think most people once they have been in the store will load up, think about it and say "Oh, let's just go home" .. particularly if the weather is warm and freezer goods in the boot of your car.
I feel like Panther, they are not quite as good as the others at the moment. I did actually go to the one in Blackburn yesterday because it was convenient on my way out, however, didn't find as good a choice (on the items I wanted) as the others. I don't think their food goods are of the same quality either. AND, they had run out of my brand of fags .
had to call at the Co-op in Clayton.
