Edgar Watson Howe:

One of the most difficult things in the world is to convince a woman that even a bargain costs money.

I ended up with a house full of things I didn’t need or want that my girlfriend had bought because they were cheap. For some reason I couldn’t convince her that just because they had knocked 50% off the price didn’t mean that it was a bargain. It only became a bargain if we needed it and more often than not it was just used as ammo for her argument about buying a bigger house!
