I'm a trade-me whore (it's a NZ auction site like ebay sorta), and I've found so many excellent buys... I scored a baby pink babydoll top that i've had my eye on for AGES, retails for $55... got it for $5
Never been worn, nothing wrong with it, just a gift the seller didn't like...
Oh and a pair of black pants down to $30 from $225 *cha ching*
I don't get to the thrift shops like I used to, but I've found Diesel jeans, Mavi jeans, jackets, skirts, all sorts of things for $5 which is great when they retail for $75 and up.
