I worked at Wal-Mart in Canada for seven years when I was younger and during the summer, when I worked more hours, I would see the department managers and the upper level store managers do it every morning during the week. Wal-mart really pushes the idea of winning. Everything is about being the best at generating profit and beating the local competition into submission. The location I worked at completely destroyed a Zellers, Eatons, Bi-Way and possibly others that I'm forgetting.

I worked in the electronics department and my manager had the discretion to price big new movie releases below the competition (he would actually check out the competition himself). We had a line that snaked through the entire store for days when Titanic came out since we had the best price for a large radius. Having the best price on an item would be something that would be mentioned during the morning meeting and would be something everyone in attendance would get excited about.
