I've just been to Big W in 2 locations (Doncaster - VIC and Forest Hill - VIC) and they are running a clearance on a lot of clothing.
Most of the clearance items were $10 though a few were marked at $15 and some at $7.84 or something.
There was sportswear (including cool dry pullovers, biking tights), casual wear (including jackets, tshirts and vests), womens shoes (including high heels and ankle boots), tracksuits, high visibility fleeces and some children's wear too.
I went shopping with a friend. She got some nice, comfortable high heels and I got a quick dry sports pullover.
Notes:
I'm not affiliated with BigW.
I think the items were bargains compared to similar items the two of us had seen elsewhere and the pre-sale prices.
Doncaster only had a small range of women's shoes (specifically black heels) that we found; Forest hill had many more colours and styles.
confirmed other members have confirmed this is at more locations than just Victoria
update no Slazenger gear found at sale prices at Wetherill Park
Yup, loads of winter apparel are marked down for summer range to come in =)
