Interesting - I wonder why that is? My house is in MN but my lake place is in WI and I can pay utilities at both with credit cards. My WI electric place does charge $4.95 processing, so I just threw like $200 on it the first time I paid it this year and then each month is just a credit. Just paid my card this morning for the water bill that was charged to it yesterday.
But, water, trash, Xcel, Verizon, Comcast, and...there is one more?...get autopay with credit each time they come through. Very strange.
