It may not be too “appeeling,” but the price of some bananas are rising by a few cents.

Trader Joe’s recently upped the price for a single banana to 23 cents, a 4-cent — or 21% — increase from the grocer’s previous going rate for the fruit that had remained unchanged for over 20 years.

“We only change our prices when our costs change, and after holding our price for Bananas at 19¢ each for more than two decades, we’ve now reached a point where this change is necessary,” a spokesperson for the chain based in Monrovia, California, said.

In contrast to other foods more heavily impacted by inflation, bananas have stayed relatively affordable over time — with average global prices never exceeding more than about 80 cents per pound (0.45 kilograms).
