I visited the WM HQ last spring.
One thing is for sure, they don’t spend money on non-essentials.
The HQ building looks like a state prison with a large number of huge metal buildings surrounding it.
When potential supplier shows up, they’re bound to think “these guys really are about low cost”
Bentonville? Yeah. Most of the 2nd floor are “cubicle rooms” where every supplier/manufacturer has to make a presentation to a WM liaison and “prove” they can meet costs and provide the product IF approved. Its’ like here in Hollywood, you have to pitch the idea.
