In store only, but every store in my area has this on Clearance for at most $30. A few have it for roughly $10, though (one as low as $9.50). Bought one for my dad for a late Father’s Day gift and it seems to work great. It says on the box that if you pay for a month of service through Verizon it will then be unlocked to use with any carrier.
