NEW YORK (CBS) - Starbucks is raising prices on some of its drinks by 5 cents to 20 cents starting next week, and customers can also soon expect to pay $1 more for the packaged coffee it sells in supermarkets.

The Seattle-based chain also raised prices on some of the drinks sold in its cafes a year ago. The latest hikes don't seem to be driven purely by the surging bean costs that have pressured other coffee sellers to raise prices, however, since Starbucks has said it already locked in its coffee contracts for the rest of this fiscal year and much of the next.

In March, CEO Howard Schultz said during an interview with Fox Business that Starbucks had no intentions of raising its prices.
