If you're a member of Woolworths' Everyday Rewards or Coles' flybuys scheme, you'll be used to receiving regular emails promising "special" offers and "bonus" deals that are just for you. But don't delude yourself: 9.5 million Australians are signed up to those schemes.

Enrolling in Qantas' Frequent Flyer program via the Woolworths Everyday Rewards scheme is, as we've pointed out before, a good way of avoiding the Qantas sign-up fee. However, make sure you check the details carefully, or you might find your points automatically converted into Woolworths vouchers rather than flights.

Coles' FlyBuys has recently joined Woolworths' Everyday Rewards in offering "activated rewards": deals which only apply if you click on a link to activate them and then spend a specified amount of money within a specified time frame.

One of our more frequent complaints around here about the Everyday Rewards scheme offered by Woolworths is that it doesn't include liquor chain Dan Murphy's, even though Woolworths owns it. That's about to change, albeit only for the month of December and only for wine.

You can already accumulate Qantas Frequent Flyer points on the Everyday Rewards card when you spend money at Woolworths, Woolworths Liquor and Big W. Now liquor chain BWS is also on the list, and electronics retailer Dick Smith is soon to follow.
