Let me tell you about an amazing place. Now don't laugh. The place friends... the place is Tamworth. I know. But for serious. The op shops. my. god. I only had time to go to The Life Line store on my way back from the wedding in Gunnedah, but my very, very reliable sources tell me The Vinnies is equally amazing as are numerous other stores.
I got me this awesome vintage dress... $8.
I got buttons, $1/bag
Some cool fabric, $2
