I got a $5400 CL for the Sams Discover. I was actually surprised with it myself.
The denial reasons for delta was low score, inq's, length of accounts, new accounts etc. They seem to be very analytical as far as my EX report & score. Besides they don't need me as much as I need them "for the time being" hehe.
For the Discover Motiva it was mainly the age of account, 2 years is what they usually like from what they say.
