We get our groceries at H-E-B (this town of about 17,000 has 2 of them and they are always packed), there is also a Wal-Mart *ho-hum*
we get our “stuff” at various places
hardly ever go to Wal-Mart any more
WalMart is subject to market competition from many sources both cheaper and more upscale.
I have no fear of them becoming a monopoly in the USA.
