Deal: Grab the Moto Z3 Play & Moto Power bundle for $150 off at Amazon
Fortunately, many US retailers offer various discounts on the Moto Z3 Play more often than not. If you don't take Amazon's current offer on the Prime Exclusive Moto Z3 Play, which is getting a 15% discount, there's a slightly better deal on the same US retailer.
Amazon is selling the Moto Z3 Play & Moto Power bundle for 30% off, and you don't even have to put up with Amazon's bloatware since this is the standard version. Also, the smartphone will work with any carriers in the United States, including AT&T, Sprint, T-Mobile, and Verizon, so you won't have to worry about compatibility.
As far as the Moto Power Pack goes, this Moto Mod usually sells for $50 and should instantly add up to 16 hours of battery life when attached to the Moto Z3 Play.
