Da. I really should have waited until at least the 10th of this month before applying so that my utilization on my MilStar card reported below 30% and NFCU went down to 14% from 28%, but nyet: the guy on my left shoulder told me not to. All of the preapprovals I was getting at the start of month looked too good to pass up.
So...Discover approval for $600 and AMEX for the $500 minimum. Sure, I now have quite a few low-limit cards but at least a few of them are from big kahuna lenders.
Congrats! Keep working at it and you'll get them higher. Discover is pretty generous, so keep working on your score, pay your bills on time and request CLI on them every 3-4 months and you'll get them raised
Congrats on both approvals
