Noticed Kettle 90G chips (Chilli, Natural or Salt & Vinegar) are available for $0.90 at Woolworths - less than half price.
I don't remember seeing them below $1 in the past. They also beat the 185g bag which is 1/2 price at $2.09 (usually $4.20) and you get the smaller bags which I much prefer.
I'm not sure how long this is available for as it wasn't part of the regular catalogue, stock up for the long weekend.
Update 24/2 1:45PM - Deal appears it may be online only (although not listed as such), see discussion here.
Update 27/2 - Reports that deal is available in store, perhaps stores were just slow to update the pricing on Thursday (best to ring your local store first however to ensure that is the case).
Thanks hamza didn't know about this one, better than when big packs are on special
