As title suggests, Chobani Greek style yogurt: 10 for $10.
I found these in various woolworths already, and it's also available online.
These are generally $2.20 each!
The big tub is also on sale for $5.
When you buy in-store, once you buy over 10, they will all be marked down to $1, even if you get 15/17/25…. (doesn't need to be multiples of 10..)
