What to do with October's extra check?

I know it's only mid-September, but I have been contemplating what I am going to do with the extra pay check I will receive in October. I get paid on a bi-weekly schedule, and since there are five fridays in the month of October, I get three checks. Sure, there are plenty of things I could do to with my extra check. I could use it to pad my emergency fund and pull myself a little closer to my $5,000 goal. I could add it to my travel fund, because I'd like to take a fun trip somewhere for my 25th birthday next year (yikes!). I could also buy a few household items I've been wanting like a chair, a new comforter or a file cabinet.

But what have I decided to do with that extra check once I receive it? Apply it to credit card debt. My Discover card which would have been paid off by February with my planned $250 payments will now be paid off by November! I will apply $1,000 of my extra check to my balance and pay the remainder in November. By this time next year, I hope my extra checks will go toward something like my travel fund or to start my house downpayment fund. But in the mean time, I have to crush this credit card debt!
