The difference is that their quality has declined and others are catching up. The food bar was near restaurant quality in 2006, now it's slop at 3x the cost. You also have to be careful about date labels, my local store will relabel old inventory and add a few weeks to the sell by dare.
Also, Amazon impacts them harder because WF lost their monopoly on weird organic product.
It's the typical big company story. They grew too fast. I'm sure the supply chain is a shitshow.
