THERE'S NO MONEY IN POVERTY.  Wal-Mart goes into the convenience store business, or not?

At last, Walmart is trying to find a solution for its horrendous shopping experience.

Bloomberg Businessweek says Walmart is coming out with smaller, "express" stores that are one-tenth the size of current warehouses.

Now that companies like Amazon and Overstock are making online shopping quick and painless, it makes sense for Walmart to revisit its notoriously overwhelming stores if they want to remain competitive.

Read between the lines: the article suggests even Wal-Mart's usual clientele recognizes the opportunity cost of time.

Craig Johnson, president of Customer Growth Partners in Connecticut says, “Walmart’s U.S. store fleet is designed for yesterday’s retail wars. If it wants to capture their rightful share of today’s shopping trips they have to have a smaller format. God bless supercenters, but they are not designed to get in and out of within five minutes.”

Neither are convenience stores, which suggests that getting a gallon of milk or a bag of potato chips will still be a pain, but dry goods and consumer durables, which are less-time-sensitive purchases, don't have to require a trip to a store.

Professor Newmark comments, "Adapt or die."
