MINNEAPOLIS (WCCO) — Be prepared to shell out some extra change for your next cup of Starbucks coffee.

The coffee chain says it will raise prices on select beverages starting July 12.

Starbucks didn’t say exactly how much more you’ll have to pay, but a recent computer glitch caused the price adjustment to go into effect early. Those customers were overcharged a maximum of 30 cents.

The error has since been corrected.

Starbucks also slightly raised its menu prices last July.
