I don’t think this is available at all stores but I checked the app and there are a few that have them for this amount or similar. The store I went to didn’t have them marked at 25 cents - it was $5.25 I think but at the checkout it was 25 cents!
It’s not just South Australia- I just checked my local store in Qld and it’s 25 cents there too (it’s a bit random - Hope Island 25 cents, Runaway Bay $5.60, Helensvale 30 cents). I’ve checked some stores in NSW and they have them as well (Fairy Meadow).
What store is this? There's no such thing as Anzac Ave Adelaide, and there's two Coles stores on Anzac Highway …
