The Cash Converters in Dandenong is really good because there's two parts to it - one is where you go in and sell your stuff and the other is like an op shop where you can browse the shelves and have a look.
I loved how the DVDs were so cheap as well. They have good family movies like Harry Potter, Disney, and Pixar films for just $4 or less. I picked up two movies for $6 which was awesome.
You should go to Cash Converters if you love finding stuff from the past, like old games and toys they don't sell any more. It's also a good place to come if you're after memorabilia.
Cash Converters staff at Dandenong are really helpful and friendly, however they don't lower the price often.
It's a good place to have a look at if you've never been to a shop like that before, it's like a better version of the Salvo's.
