I'm not sure if this is considered a duplicate, or a deal in its own right…I'll let the mods/voters decide on that :) I won't be cut if it gets pulled.
So in true ozbargain spirit I went to Kmart to check out the 25% off underwear sale to see how much the Bonds Fit undies would be…turns out they had a selected range on clearance for $15!
This works out to be $11.25 with the 25% discount…then if you claim the $10 cashback as posted here: http://www.ozbargain.com.au/node/18481 - it works out to be $1.25!
I had to be annoying and ask the checkout chick to put them through as seperate purchases though (I bought 4 pairs).
Whether or not you choose to boycott Bonds is up to you, but $1.25 for comfy undies is a steal in my books!
p.s. not sure if this clearance special is available at all Kmarts, but Eastgardens had quite a few sizes/colours in stock (as you can see from my photo)
EDIT some stores also have Fit Briefs available for $13.99 (normal price I believe), which come down to $10.50 after the 25% discount, ie. 50c with the cashback! Verified at KMart Broadway, and also by user andykillz below.
p.p.s Thanks again to phildo for the awesome original post, champion!
lol at all the tightarses flocking to kmart for this offer, me included. man, every kmart was cleared out when i got there, thanks ozbargain!
