Electricity rates vary always depends on where you are and how much you'll spend. 22cents in upper MD to 10cents in many other states.
We always try to find monthly rates. Last year, we left south TX @430+elec for GA @$435+elec. Then on to Charlotte, NC @$400 (1st $100 for electric) for Twin Cities @$500 (elec included). Now we're near StL.
If we paid weekly, @$318 vs $645+elec month, we would spend much more. We happened to hit MO during a heat wave, but am sure we won't spend $627 for elec (total $1272 for 4 wks). A previous summer we did use close to $190 for one month in same location.
