Just thought of this one. Coca Cola at Officeworks is absurdly expensive (Like $1.42 per can) http://www.officeworks.com.au/shop/officeworks/p/coca-cola-c…
Next time Coles/Woolies have a sale at 58c per can and it seems like an alright deal, will Officeworks take 5% off that? Since their coke is really expensive this could be used to always score cheaper drinks (assuming they do it)
They cant deny you if the items are identical. They ll probably have a good laugh behind your back.
