Curbing inflation doesn't make things cheaper, but a few things are cheaper.

Inflation is moderating. Last week we saw the consumer price index going up 2.4% in a year versus 2.7% as calculated a month earlier.

Gasoline prices have been deflating regular now and below $3 a gallon.

The reason is basic economics, says Gernott Wagner at Columbia Business School.

once you get there. I'm Mitchell Hartman for Marketplace. I saw one calculation that televisions
