For the past few months mine has been about $60 tops. All of a sudden this month, I got one for $116! Now, we've been using the AC, and I have two dehumidifiers which I WAS running pretty much all the time (one non stop, the other would run for 4 hours, shut off for 4 hours and repeat) but now I'm alternating days to try and cut back. I would think that that was the cause, but we were running the dehumidifiers and AC during the last billing cycle too and we only paid around $60. How bad is yours?
