By a coincidence I just raised my limit yesterday. I always pay it off and treat it like cash but I raised it because I'm getting ready to buy a new tv and AVR and the limit wasn't high enough and I want to get the rewards for it rather than just write a check.
I used to always keep a low limit on it but just last year in July I raised the limit on it to get the reward from my tablet purchase I was going to do and now raised it again for the upcoming tv and AVR purchase.
