This deal may not be replicated by every one. YMMV. Go easy on me.
I called AT&T loyalty team for an issue with my account. I generally asked if there are any iphone offers with a 2 year contract. Along with the standard iphone offers, the rep mentioned that if I signup for DIRECTV NOW Go Big plan ($65/mo), then Samsung Galaxy Note 9 is free + tax. She herself mentioned that DIRECTV NOW subscription can be cancelled after 30 days. I asked at least 4 times and she confirmed every time that I am not signing any contract on DIRECTV NOW. Since it is $65 plan, DIRECTV is going to send a Roku Stick too.
1 mo of DIRECTV NOW service: $65
Tax on Note 9: ~ $35
Upgrade fee: Waived.
Note: I am already on AT&T unlimited plan.
