Whole Foods isn't a 'whole paycheck' anymore, its cofounder says. Here's what I found buying groceries.

• Whole Foods co-founder John Mackey says the grocery chain isn't so expensive anymore.
• He credits Amazon and Jeff Bezos for making changes to Whole Foods over the last several years.
• I compared Whole Foods with another grocer and found that it is cheaper under certain circumstances.

Whole Foods has long had a reputation as a pricey place to buy groceries.

No more, according to cofounder John Mackey.
