Another $6k credit limit added to my discover IT card. 3 weeks back i looked for SP CLI on this card. got a letter stating "NO" from them.
Yesterday, got an email stating, your request for credit limit increased.
it jumped from $32400 to $38400. woah..
i love this love from discover. 
actually i m reducing my discover usage from $800 per month to sub $400 usage starting this month. planning to use the amex pref bce more for its rewards.

Congratulations!
Thank you. yes, i did felt the same way. this card consistently getting 6k increase every now and then. i have another discover card, which usually gets max 2k-3k cli.
