Where is a good place to get purses?

Okay so I'm looking for a swing pack. (The ones with long straps to go across your body) but all the ones I find are super expensive. Where can I find discounted swing packs..? I really like the brands coach, harijuku, bettsy johnson, juicy couture & dso on but if you know of a site with really cute ones that aren't that brand still leave a comment!(: thanks in advance.
