What an awesome approval!! The IT seems to be a well-loved card. Congrats!
Congrats on pulling the trigger! $9K is double what I started out with and seems to track with a couple of other approvals I've seen lately.
You should have the card possibly by the weekend if not by Monday. When you sign up online for an account you can activate there as well IIRC. No worries though as you're on the road to DiscoverY. This will be your 2nd xmas though when you get the package
