The current Women's Weekly (with Ellen on the cover $6.95) comes with a $20 "gift voucher" for Trenery stores. Expires 31 March. No minimum purchase mentioned.
It's between pages 130 and 131. It has to be used in store only so this sort of limits who can access this deal but figure it's still worthy of a mention.
If you buy the magazine in Woolworths you will get also get a free L'Occitane Dry Skin Hand Cream 30ml (seems to sell for about $12) which smells nice and contains shea butter.
Edit: Uploaded the L'Occitane coupon offer too - spend $60, get $25 gift - plus picture also shows the freebie hand cream from Woolworths.
