the search for the shoe...

Let me begin with: I am a shoe whore. I love shoes. I really love cheap shoes, because then I don't feel bad when I never wear them again... So, the search for cheap wedding shoes begins... Any suggestions? My dress is ivory... I want a low heel... I want to spend less than $50 on them, and my mother (who is paying for a major chunk of the wedding) has said absolutely no flipflops... I need shoe advice! and quick!
