I love "Swap" ( please, take a look http://events.swap.com/ ). It's a shopaholic heaven without $ guilt.
All you need is a good eye, and to be fast. First come, first serve!
My swap score was unbelievably good this year! I found everything that I was wishing for.

Also, I got all the outfit (post) below: a bohemian print floral dress and a velvet cape (best find ever- I was dying for it).And good trendy (and vintage) items: red leather jacket, Dior wide leg, kimono jacket, and maxi tribal print dress. Upcoming pictures!
I'm ready for Fall!
