Congrats. Don't want to put a damper on your happiness but just a word of advice-be cautiously conservative when you request CLIs with 4 Synch cards. The dreaded blue envelope seems to happen to people who either request a lot of CLIs or that have multiple Synch cards. I have no scientific proof of this just my observation-and as with all credit stuff it is a YMMV thing. That being said-its great you got such good CLIs and you have had your Amazon card for a bery long time so that helps too I would imagine. Just be careful and if it were me I would only request increase if I truly needed them.
