This is the Badassity forum, but I'd like to give you an example of something stupid I did, and how I got it corrected. Maybe it could be called slow badassity?
We have the option of buying gas and electricity directly from the producer, or through various secondary suppliers. These secondary suppliers offer teaser rates for the first year, and then, in my experience at least, jack up the rates considerably after that first year.
So, my dumbassity, I forgot all about it, and didn't question my rising bills for oh, let's just say 'several' years. I got fed up when my August electric bill shot up to over $180 bucks (double our next highest month), and we NEVER use AC, and almost never use a clothes dryer.
My wife keeps careful records, so I went back over the last few years and noted that every summer it is the same pattern, huge costs, which then drop back down in the fall again. So I call the local electric co and ask their current rates. Shock. Much lower than we were paying. Got my supplier cancelled and back on with the electric company.
Now, the real dumbassity portion. I didn't check my gas bill, until last week. Secondary supplier cost was literally double what direct purchase would have cost. They tried to offer me another teaser deal, a pretty good one actually, but I just don't like to work with a company that screws me once. My own fault for not checking, of course, but still, I let them screw me.
Just a hint, check your costs occasionally, against what other possible suppliers might offer. The teaser deals are fine, for people who are more methodical and better organized than I am.
