While looking for the T&Cs of the 10% off Big W cards I noticed this pdf deal.
So 5% off all gift cards on their site, the classic WISH eGift Card makes the most sense, no delivery fee,can be used in all Woolworths associated stores, can be used to buy a physical card, unless you get a combative teller. Can be used to buy all gift cards for other stores (JB, PSN, iTunes etc..)
If you can't get the Big W ones, or they turn out to be just Big W, or you don't want to use the Cashrewards link to alway get 5% off because, well I have no idea why you haven't been doing that already, then here is another option.
