If it was only THAT easy...
Let me give you a reality check...
Walmart is pushing competitors out of business in large portions of the country. That they can do due to their practices which get them in trouble with the law times and again. For them it is cheaper, which is more profitable, to pay fines to the federal government instead of fixing the problems and not getting fined at all.
Once a competitor got pushed out of business an entire region has but one alternative, for both... Job and shop..
WALMART..
We had a Pamida here in town... It closed. Guess who's next closest?
you guessed right.... Walmart. 20 miles away. next Pamida? 35 miles away.
