IGA gift cards can be used at participating IGA supermarkets around Australia. IGA gift cards are usually included in a handful of 10% off promotions throughout the year. Unofficially, IGA gift cards have been reported to work at other stores in the Metcash group (e.g. Cellarbrations, Mitre 10 etc).
There are two variants of IGA gift cards: Eftpos-based cards that you have to physically swipe to use and those with a barcode that is scanned. Not all stores accept both versions.
