Dates and availability: Pre-order, release date, carriers, retailers

Samsung has announced that pre-orders for the Galaxy Note8 will begin on August 24th. Pre-order dates may vary by carrier or retailer, but most will probably start then.
AT&T, Verizon, Sprint, T-mobile, U.S. Cellular, Cricket, C Spire, Straight Talk, and Xfinity Mobile will all be stocking the Note8. Retail availability for these providers in physical stores will begin on September 15th, though pre-orders may ship before this date (as often occurs). You'll also be able to buy the phone direct from Samsung, Best Buy, Target, or Walmart. Samsung will be selling a completely carrier-unlocked version of the Note8 on its website that will work on all four major US providers, too.
