Currently there are red "50% off Selected Mix Clothing" signs posted all over the Mix clothing section at Coles in Epping, NSW - not sure if this is the same at other Coles stores that sell Mix apparel and this offer doesn't appear online.
However, from what I can gather, the discount actually applies to all Mix clothing (even sale stock) and after a discreet look at the notice stuck on the register screen of their refunds counter, the sale is on until Sunday.
I didn't take pics but basically this morning I got:
* 4 x t-shirts ($8 each)
* 1 x singlet top ($6 each)
* 1 x long-sleeved top ($10 each)
and this came down to a total of $24 (from $48).
I also used a $20 Coles Mix Apparel in-store voucher redeemed via the Flybuys website (for $10 worth of Flybuy points), so I only ended up paying $4 in cash for the above purchase.
there's 2 coles near me that sell the Mix clothes, and both have closed down that section. No signs if they're renovating them, and i asked a couple of the workers and they said they weren't sure
