Next week my son and I are planning on riding bike (actually I will be pulling him in the chariot) from Columbia to St. Charles, MO on the Katy trail. Snickers bars are on our "list" for necessities for this trip. This week, while shopping at Wal-Mart I put a six pack of Snickers in my cart. The price was $3.68. While checking out I see that Snickers are 50 cents a piece right in front of me in the check out isle. Both of these prices appeared to be the regular price, neither were on sale and they were the same size bar.
Questions - Why does the largest company in the world have a product that, the more you purchase of the given item, the more expensive it is? Do people notice?
