Neg me if I'm wrong, but buy any item in the current BIG W 'Sale' <a href = 'http://catalogues.bigw.com.au/portal/dynamiccatalogue?CatalogueID=12750222328947&pageview=two&gotopage=1'>Catalogue</a> and scan your Everyday Rewards card to receive your 100 points. Besides other promos, you would normally need to spend $130 to receive 100 FFP.
There are selected John Sands cards in the catalogue for $1.
I "activated" this deal in an email I received from Everyday Rewards, so you may need to be a subscriber to the email offers in order to be eligible.
I got the e-mail too, the link is the same as yours, so I doubt it's anything different.
