Blackberry has cut prices on its flagship smartphone in a bid to boost sales.
Blackberry has cut the price of the Z10 phone to as low as $49 with a contract - down from $199 four months ago.
Blackberry is battling to revive its share of the smartphone market with the touchscreen-only Z10, which shows off its new BB10 operating system.
Users can get the Z10 through US carriers AT&T and Verizon Wireless, for $99 with a two-year contract, but the phone costs $49 with a contract at retailers Amazon and Best Buy.
Blackberry reported an $84m loss for its last quarter and refused to say how many devices running BB10 it sold. Blackberry has said it shipped one million Z10s in the first three months of 2013.
