I didn't see it in the Coles catalogue, but during my weekly shop I noticed the 700g Mutti Passata varieties were $2.50, down from $3.50. I picked up a few bottles, the basil one in particular is quite nice.
According to PriceHipster it used to get promoted reasonably frequently but hasn't been this price since Feb - there's a good chance this reduced promo frequency is here to stay given Mutti's strengthening brand. Worth a stockpile of an OzBargain favourite if you can get to Coles before Wednesday.
La Gina Passata $2 a bottle at Woolworths currently.
