So I read all this and figured what the heck. Here's how it went:
-Citi Driver's Edge Platinum Select card, opened in March with $4000 CL, luv button gave me $1500 increase to $5500 a month ago. No hard pull.
-BofA AMEX, opened August with $4100 limit. Filled out the form Sunday on MBNA net access. Bumped to $5500 on Monday (it was all I asked for). NO HARD PULL.
-BofA Visa Platinum-opened August with $5250 CL, got a message that the account is too new.
For the college students: I got these cards and limits three months into my first job, no previous credit history except student loans not yet in repayment, and at my current residence less than one year. With Citi, I applied for the student version and they approved and sent me the regular platinum version. Wish I had known about CardOffers though-missed out on some cash. Hope that helps any students lurking.
