2 Steps forwards, 1 step back

So yesterday was a good day. Financially I felt like I was ahead of the game. I had to put new tires on my car and was able to pay cash for it. (YAY!!) Later in the day I was balancing my checking account and looking at my budget, and realized I had about $50 extra to play with this month, so I threw another $30 at one of my CCs through bill pay. Today is another story...I checked my account online and saw that I had a $10 balance, not including the $30 payment I made to the CC yesterday. So what happened to that $40? Damn Toll-tag payment...seriously those things always sneak in when you're not expecting it. And it's not like a regular bill that hits when I know it will! For those of you who have never had a toll tag, the way they work here is that $40 is charged and credited to your account. Each time you pass through a toll booth, they deduct from your account...when the balance hits $10, they charge another $40. So depending on how much I've had to rely on the toll roads, i get billed anywhere from every 4-12 weeks. Luckily I used bill pay through my checking to send the $30...since I don't have the $$ in my account, the bill pay will just get rejected (no fees, no returned checks, etc.). And luckily it was and extra payment, not my actual payment.
Good news about the toll tag is that it will be basically irrelevant in within the next 60 days...I only use the toll road to get to work, and my office is moving in Nov...I won't have to take the tolls to get to the new location. (I could get by without taking the tolls now, but the extra time sitting in traffic probably wastes more than $0.35 of toll charges in gas.) In the mean time I tracked down the website where I can track my TT balance...i'll just have to stay on top of it now.
