The electric and gas company here is too bad at billing to really know what we pay.
Last month we got two gas bills for $20 each and no electricity bill.
Then this month they sent one gas bill for $16, but it was covered by the last month's redundant one - so they owe us $4.
we had one electric bill when we moved in, and none since.
but when they do send it, I would guess it is between $60 and 150.
as long as it is under $180, then I'm happy.
I purposely haven't had all my computers on though since the AC has been on a lot lately.
