Kinokuniya in Sydney is offering 20% off books for members. (Membership is $15 for one year and $25 for two years).
I was buying a bunch of books anyway and getting the $15 membership overall made the purchased cheaper than just getting the purchase. So it's a deal if you're buying more than $75 worth of books or if you want the membership for a discount amount.
The card usually offers 10% off purchases.
Either way .. there's some kind of deal in there … you work it out.
