Amazon has also undercut manufacturers a few times during the holiday shopping season. For example, the Galaxy Watch 7 is still full price ($349.99) at the Samsung store compared to Amazon’s 17% discount. That won’t be the case when Black Friday kicks off in a couple of weeks, but if you’re looking for a deal today this is a good offer.

When it comes to Black Friday, Amazon is taking center stage. The retail giant just announced its official Black Friday sale will begin on November 21 and run through December 2. From Dyson and Levi's to Hot Wheels and Ninja, you can expect tons of massive markdowns on your favorite name brands.
