I bought a house, a real fixer-upper :) One problem is that a lot of the holes cut in the drywall to fit around the receptacles are too large, so that the fins on the plug don't catch - it just keeps going till it's flush with the box, which of course if flush with the stud. So, the plug sits about 1/2 inch too deep.
What are some methods for fixing this? The best way I could think of is to buy some longer screws, and some small, thick washers. Any suggestions?
