Why it's a good deal: You can get one of the year's best smartphones for free. T-Mobile is giving away a 32 GB Samsung Galaxy S6 for $0 down and $0 a month for 18 months. It normally retails for $580 or $24 a month.
Fine print: You have to sign up for T-Mobile's Jump lease plan and trade in the phone (for a new phone) after 18 months. If you want to keep it, you have to buy it. The deal is valid between Thursday and Sunday while supplies last.
