When I was at our local Coles yesterday, I noticed that they had OOB frozen blueberries and mixed berries in the specials display at the end of the freezer aisle, which my wife uses for her breakfast smoothies, for an unbeliveably half price special of just $4.85 a pack.
I told my wife and she asked.if all varieties were on special so I checked the freezer aisle today where thay were all on special at 2 packs for $12, save $2. I looked under the special sign and the new normal shelf price was $7 a pack.
I bought a pack of blueberries and they actually scanned at $4.85 so I missed out on a freebie, but the entertainment value compensated for that.
Perhaps if you buy 2 packs, they are $12 but if you only buy 1 pack, the price is only $4.85.
Not a very good multi-buy.
PS. Shonky alert. I just noticed that the $4.85 packs are 450gm and 500gm but the 2 for $12 packs are only 300gm.
