If you have say a 700/25 tire, get an 700/18-23 tube.
If the tube is too big, it increases the odds of pinch flats. The bike guys at MEC will know all this. It is pretty common knowledge to size down your tubes if you can.

I wouldn't recommend that. Just buy the proper sized tube for your tire. I've spoke about this before from members of my cycling club, and nobody does that.
