Ahead of some big Black Friday deals coming this week from Best Buy and just about every other retailer, the best deal to get your hands on a new Galaxy S4 on contract is already available. Starting today, Best Buy is offering the device on most major carriers for $0 on the usual two-year contract. If you already planned on signing up with the devil for two years to avoid the $600+ retail cost of the S4, you definitely won’t be able to find a better deal than this. Currently available for Verizon, Sprint, and AT&T, BestBuy has the S4 in Blue Arctic, Black, Purple, Red and White, and is also offering the rugged Galaxy S4 Active on AT&T in both blue and gray. The deal is available to new customers, but also for those adding a new device to an existing account or upgrading with a two-year contract extension. These devices usually run $199 – $249 on contract, so you’ll want to take advantage of this deal today while it lasts.
