Hey - about those running toilets? Not so hard to fix, usually.
If you have the kind of toilet with an arm with a big balloon thingy on it floating at the top of the tank - sometimes you just have to slightly bend that metal arm so the baloon thingy sits higher.
Or - sometimes the flap at the bottom of the tank isn't sealing. Try resetting it manually. If part of it is torn, or you just can't get it to seal properly, you can get a kit to replace the tank innards at your hardware store - not too hard to do it yourself.
Get yourself a good all-round home repair manual with good pictures. You'll be surprised at what you can fix yourself.
