Sometimes I like to shop at Walmart just for the people watching!
Walmart also owns Sam's Club retail warehouses all across the country!
I was at Walmart the other day, and they had car batteries fo $30. I need to remember that next time I need one.
Walmart denies wrong doings and says that low prices are the result of hard work and efficiency. 
Well they seem to aggressively negotiate contracts with their vendors as well.
Walmart even has a Canadian division called Walmart Canada Corp!
Oh Canada! There is a company in England called Tesco which is very similar to Walmart. I walked into one last time I was over there.
Zellers Inc is another major Canadian chain department retailer. It is based in Brampton, Ontario.
It's just too cold up there for me.
Maybe you could buy a parka at the Target Canada Co., which is the second-largest retailer in the United States.
