Hello. Aura Blue will be exclusive to Samsung and Bestbuy. Right now there's no SKU for the Aura Blue N10+ (ATT) at BB. Unfortunately I don't have any info regarding future availability.
According to the Note 10 press release blue will be available for the unlocked and carrier variants: "Galaxy Note10+ will be available in Aura Blue exclusively at Best Buy and Samsung.com, in carrier and Unlocked by Samsung versions in the U.S. Pricing starts at $949.99 for Galaxy Note10, $1099.99 for Galaxy Note 10+ for both carrier and unlocked versions."
I went to Best Buy website today and was gonna order the Glow (I don't like it as much as everyone else seems to but didn't want another black phone) . Wishful thinking I selected the Aura Blue and IT'S AVAILABLE FOR AT&T NOW! I ORDERED IT IMMEDIATELY!! It wasn't a couple days ago.
SOOOOO HAPPY I DRAGGED MY FEET ORDERING!
