Coles have a sale on all Armor All Car Care products and a couple of Polyglaze products aswell at Coles Northland in Melbourne so I'm not sure if it's at all stores Australia wide.
When you buy 2 of the same Armor All products you get 25% off both items.
It's not a bad deal as I just bought two 500ml Armor All Glass Cleaners to test out this deal and they gave me the 25% off both items which is pretty good.
I just checked out Supercheap Auto online store for this same item and they have the glass cleaner for $10.99 each. Coles have it for only $8.98 RRP. If you buy 2 you only pay $6.73 each during this sale. That's not a bad deal at all!
I don't have a camera phone to get any instore pictures but they have the yellow sale labels under all the Armor All products and some Polyglaze products that they have on the shelf and there is quite alot to choose from.
Cheers!
meh only 25% on the condition that you buy 2? Their buy 2 get 1 free deals were better value. I don't consider this a bargain
