That particular configuration is not officially available stateside from Motorola or major third-party retailers like Best Buy, mind you, which are instead charging the aforementioned $250 price for a G7 Power version packing only 3 gigs of memory and accommodating 32GB of content before adding a microSD card in the equation. In other words, you're looking at saving a lot more than 52 bucks, although you also have to consider a couple of downsides before pulling the trigger.
For one thing, while the units on sale today at Woot are completely new and unused, they come with a modest 90-day seller warranty rather than the manufacturer's full 1-year coverage. You're also looking at GSM-only factory unlocked devices here you should be able to easily activate on the likes of AT&T and T-Mobile, but not Sprint or Verizon.
All things considered, though, it's hard to argue with a monster-battery phone fetching less than $200 while sporting an extra-large screen, decent build quality combining smooth plastic and tough glass, a fast and reliable rear-mounted fingerprint scanner, and squeaky clean Android 9.0 Pie software. The 4GB RAM Moto G7 Power is up for grabs at $197.99 in blue and violet hues, but based on a similar Woot deal from last month, you don't have a lot of time to act before the price goes up or stocks run out.
