Inflation is falling but buying food can still be expensive. 

Grocery prices have risen 21% in the last three years, according to the Bureau of Labor Statistics. 

Andrea Leo owns Sun Market grocery store in Denver, Coloradom and says she does her best to keep food prices low, so customers will continue to come in.

WHY ARE GROCERIES STILL SO EXPENSIVE?

"Sometimes I pay more for potatoes than I am charging. Same with milk. I make like 10 cents on milk. But it's more important for me to have it affordable so that people can come in," Leo said.

Leo said inflation had the biggest impact on the grocery store prices of her poultry and produce. To help, she donates some for free to families in need.

"I want to have something for everyone. No matter what their budget," Leo said.

Dr. Kishore Kulkarni is an Economics professor at Metropolitan State University of Denver.  Kulkarni adds even if you don't notice a price hike, you should watch out for shrinking products. 

"We should look at the packets. Make sure that your product size has not gone down and you are paying the right price for the right product," Kulkarni said.

Kulkarni said inflation is hovering between 2% and 3% nationally, but economists say some food prices remain inflated by up to 10%.
