Approved for Marvel last week with a disappointing $1k SL.
The card hit my CR within a couple of days with a $1k SL. Today I received the card and it said $3k SL, so I was confused. I looked at my CR and it is now listed as $3k. Then, I logged into the online account and it said $1k SL. I then called to activate the card and the auto line told me it was a $1k limit. I logged back into the Marvel online account, after activating the card, and my credit limit changed from $1k to $3k. Soooo, Marvel tripled my SL before I even received the card and I did not call or request anything. Not bad.
