Deal: Buy a Moto Z Play, get a free JBL speaker
Unfortunately, the Moto Z Play is no longer available for $50 off (as it was earlier this month), so it currently costs $449.99. Nevertheless, you're still looking at a $79.99 save - that is, of course, if you're finding the JBL speaker useful.
To actually see the $79.99 discount, you'll need to add both the Moto Z Play and the speaker to your cart, and enter the code FREESPEAKER before checkout. Mind you, the deal is available only via Motorola's website, and only in the US - see the source link below. Also of note is that Verizon's Moto Z Play Droid is not included in the offer, only the unlocked Moto Z Play is.
