Positives:
Very good prices,
Stores are a nice and easily navigable size
Negatives:
Customer service is not their forte (checkouts are a nightmare)
Their own brands are deceptive similar to existing ones (e.g. Bramwells vs. Branston)
Not all products are as good value as they appear.
Shelf fillers not aware of own surroundings. I've been pushed aside by them a few times.
I won't be returning.
