I noticed on my report a soft inquiry from Lowes/GEMB, so I decided to hit the LUV button today. Instantly went from $4,500 to $9,000! I've had the card since 2007 and started out with a $1,200 CL.
Sears and Menards also soft pulled me within the past 3 months, so I hit the LUV button with them as well. The online form at Sears asked me how much of an increase I wanted, so I put $2,400. I pressed submit and got the message "You'll receive a response from us via U.S. mail within 7-10 business days". I logged out of my account, logged back in about 30 minutes later, and my CL had increased from $4,600 to $7,000!
Menards was an instant increase from $4,400 to $5,300.
Not a bad day! 
Congratz. Do you mind me asking if you know what your scores were when you were approved for the increase? Thanks!
