Well, that was fast. One day after Samsung's big Galaxy S8 reveal, the phone is now available for pre-order at Samsung's website and all major U.S. carriers. We already knew the pricing for both the S8 and the S8+, and there are no surprises here. But why dish out your cash now only to get the device on April 20? Samsung's got at least one good reason: All customers who pre-order the Galaxy S8 or the S8+ before April 20 get a free Gear VR with the new Controller for free.
