I'm not sure if this is store specific but $1 chorizos at Central West Plaza Vic. Usually $3 each and on occasion half price. I have not seen them this low.
Here is a link to an awesome chorizo stew, I also add chicken.

Good price if you are in the area but it'll be just a store specific deal, maybe due to end of display life? The other week I picked up bacon for 50c/kg, cabanossi sticks for 5c each and all olive/sundried tomatoes/etc varieties for $1/kg at nowhere near expiry at Coles Toombul and this was the reason they gave me. It made enough pizzas for a month!
