I live with 3 other guys and go to university part time. The guys and I all are a bit tight on funds. So we are agree to save cash however we can. My take napkins and condiment packages from restaurants. I take toilet paper from the university bathrooms all the time. We also are really stingy when it comes to Heating and Air Conditioning. The house we rent has central heating and air, we just never use it. The cost of running Heating and Air Conditioning is super high. In the fall and Springtime, we can get by with no form of climate control. The weather changes daily anyway. We just dress a little odd depending on the temperature. In the Winter we are forced to use some type of heating device. We use several space heaters. One oil furnace in the entryway and 1 in the bathroom. The reason those rooms get heating is due to piping. We don’t want the bathroom or entryway piping to freeze and then burst. That would be a hefty plumbing repair. Then we go several to a room and get a portable oil furnace in the room. The cost of electric of course goes up, however it is cheaper than running a central heating system. We don’t worry about the whole household being the same temperature. We also just heat enough where we don’t freeze to death. In the summer time we don’t even bother with AC. Yeah, sometimes mold happens however we simply clean it up and run the dehumidifier a little more. For cooling needs we go to sizable dealers and hang out or to the local pool.
