Got this from the Markdown Australia group on Facebook. This started yesterday and has been "smashed". However, there are some remainders. YMMV
You need an item with a "W23" tag on the item's bigw sticker. Or a yellow circle $1 sticker. Attached pic of the tag as people were missing this on the last group. Check each aisle eg socks and also the clearance areas. You can also download the Big W app and scan. If not found then good chance it is deleted.
Rough areas are:
Tradie underwear (Mens and womens). Normally $10 -$17. Better luck with Womens as mens has been posted last two days online.
Edit: it seems Boys and Young Girls items are available as well.
Star wars Boxers and Socks
Spiderman Boxers
Blacksmith "tough socks" camo print
Underworks "Heat bod" socks ($3 a pair at Woolworths if you miss out)
There are more items marked down. It is nationwide, but some stores have more to discount or are discounting further (S23 items imo). If a store doesn't discount s23 or rpl codes, there is a chance they might this week or so to follow the other states.
Saw on markdown addicts yesterday. Had a look today in my local store and couldn’t find anything.
