Greg Mankiw quotes Michael Barone’s attack on John Edwards:

His stump speech includes a line about a little girl whose parents couldn’t afford a winter coat. Give me a break. You can buy a little girl’s winter coat at Wal-Mart for $10. That’s the price of taking the little girl out to lunch at McDonald’s.

But Brad DeLong writes that “neither Greg nor Barone shops at Wal-Mart often enough to know or surfs on over to the Wal-Mart web site to learn what girls’ winter quotes actually cost,” pointing out that the winter coats at Walmart.com actually cost $20-$35.

Along the same lines, has Barone ever eaten at McDonald’s? Two people can eat lunch there for way less than $10.
