Grazia at Woolies has a free Modelco eye shadow attached that is allegedly worth $39. Inside they also have a discount code valid until 26 Dec. It is for $20. Modelco appears to be currently offering free shipping until 21 Dec, EXCEPT when you use this voucher. When you use the voucher, it subtracts up to $20 and adds $10 for postage. Effectively it is a code for up to $10 value. I bought an item for slightly less than $20 and it took off the product cost only, therefore the code is not valid for postage.
The information says it is not valid for sale items, but it does discount items under "gifts" which are sets that are bundled at a discount. For example, there are two sets for tanning items that are for sale at $19, with an alleged RRP of $33. Therefore, you would be getting an alleged $33 worth of product for $10.
The Grazia code is Grazia-20
Cleo magazine has a similar freebie item with a $20 voucher code, that code is Cleo-mc and it appears to have the same constraints.
Grazia is $6 and the card says that the eyeshadow is a "Woolies exclusive".
Don't remember the price of Cleo.
