Walmart has phased out a lot of firearms in stores and from what I hear the ammo is the next to go. The guy in sporting goods told me that orders were not being delivered and it was NOT the suppliers fault !
If they are doing this nation wide {likely are as they still limit per box sales in my area} then they will indeed become the next K-Mart of Big Box. Simply meaning there and hanging on but few even notice. You're right. I have notice Walmarts in my area carry no where near the ammo stock and VARIETY of such they once did. This trend had started before the shortage BTW. The market is going to be ripe soon for a suitable Walmart replacement just as Walmart replaced K-mart at the top of the list.
Sam Walton was out to make money and there is nothing wrong with that if done ethically and honestly. The current management of Walmart seems to be out to deliberately destroy the company and anger and in some policies like layaway closure hurt as many of their long time customers as possible.
Bentonville Corporate Management is detached from reality and their customer base. If policies aren't reversed I don't give Walmart another 5-10 years tops before we start seeing Walmarts closing as fast as they were once opening at their peak. In the mean time they were a main force in driving U.S. manufacturing to China and Mexico so I say their corporate fate would be a just one indeed.
There's several threads in the past week or so and many besides myself are seeing the same overall general detioration of Walmart. If Costco {??} would move into areas like Knoxville, Chattanooga, Tri-cities, Tennessee and the East Tennessee, Carolina's, Kentucky, and Georgia, area for example they would get the business. Walmart is already on a decline there and any new full service Big Box would likely easily fill the void Walmart has created and drive them out.
