Lucky find with these coupons contained in the current Harris Scarfe newsletter, whilst I was looking online for a Harris Scarfe code to buy this awesome mandoline slicer currently just $80 on catalogue sale starting Wednesday (http://www.harrisscarfe.com.au/borner/borner-v6-stainless-st…) … yes I've done my research, it's the cheapest price around.
PDF includes various coupons for October, November and December.
The $20 off $100 spend is only available for the 3 new HS stores listed (Elizabeth, Colonnades, Carindale) with a very long expiry date 1st January 2015 … so if you shop regularly at these stores, I don't see any reason not to print as many coupons as you want (does not state original coupons are required).
Some require you to be a HS card holder / requires an original coupon (e.g. Reward Dollars) but I am guessing anyone can use the coupons that say GUEST on them. There is no other fine print on the GUEST coupons, so should be good to go.
*Also note that it looks like the VIP 5% / 10% coupons are for specific dates only : 18th November and 16th December (good Xmas timing!)
Enjoy!
