Trader Joe's raises banana price for the first time in more than two decades

Trader Joe's customers may experience sticker shock the next time they buy a banana —after more than 20 years, the retailer has hiked the price for the first time. 

The price of a single banana has gone up roughly 20%, rising from 19 cents each to 23 cents. A company spokesperson said that Trader Joe's only changes its prices when costs change. 

"We've now reached a point where this change is necessary," the spokesperson said.
