Coinstar, owner of the Redbox movie-rental kiosks, said higher prices for its rentals lifted first-quarter profit.

Net income rose to $53.7 million, or $1.65 a share, from $8.5 million, or 26 cents, a year ago. Sales rose to $568.2 million from $424.1 million.

Coinstar benefited from higher prices for Redbox rentals and lower-than-expected debit card processing fees. In October, Coinstar raised the price of a nightly rental cost for standard DVDs to $1.20 from $1, blaming fees.
