I've never been to a Target but in general, places like that are much. much bigger than what we generally have up here and have better selection.
Target tried to make a big expansion into Canada but people found that the selection was miniscule compared to the US-based stores and pricing was not close to being equivalent. They started out with most stores having lots of empty shelves, lacking stock, and they never really got off the ground. They gave up quickly and wrote off billions of dollars.
Anyway, last time I was down in Washington State I stopped at a Walmart and it was very clean and pleasant (skylights, great lighting) and much bigger and better stocked than what I'm used to. The oil and filter section was like heaven.
