A couple of points from articles that coincidentally appeared in my local newspaper this week.
One said that 60% of McDonald’s sales come through the drive-through window.
The other article talked about how the major local supermarket was responding to the presence of a Wal-Mart supercenter in town by switching away from its old policy of big sales in favor of one that featured lower prices throughout the year. One thing that was specifically mentioned was that 2-liter bottles of soda would no longer go on sale for 99 cents as a loss leader.
