Best Buy
The Best Buy app is one of the smoothest, most comprehensive shopping apps out there. Unlike the majority of other retail apps, this one is clearly built with the DIY-enthusiast in mind, making it a fantastic addition to your arsenal of shopping utilities for Black Friday. It features a QR scanner that can be used to view detailed information about products in-store, as well as build a wish list. There are detailed reviews and ratings for products available as well.
