Funny(well not so funny) story. I got my electric bill after we had been running the tent for over a month (lights and fans to keep heat down) and it was $100 more than previous month. I freaked out. THEN I realized that my one year contract had run out previous month and my rate had skyrocketed. I immediately when online and signed up with a new supplier. Damn, that high usage hit same month that my rate went up. Of course, I went back and found the notice that I had one month left, but since I pay online I don't usually open extraneous mail from them except the bill which comes in a blue envelope instead of plain white. I'm an idiot.
