Thanks to kitsch for this original deal. Seems to be expired on Amazon AU but Harvey Norman still seems to have plenty of stock in Melbourne stores at least.
Or get Chemist Warehouse to price beat to $7.50 each in-store, like I and narm did. They had to manually override in the Bourke Street, Melbourne CBD store and matched it first. Had to point to the 10% price beat policy to get them to change.
Credit to NotBritishorUK for mentioning the deal in comments.
Sorry but how did $10 becomes $7.5?
It is 10% price beat right?
