Coles currently have 20% off iTunes and Apple Music gift cards.
The stand out bargain here is for purchasing the 12 month Apple Music subscription. You already get 12 months for the price of 10 with this gift card ($119, saving $24.88), so with the additional 20% off this becomes $95.20, equivalent to ~$7.93/month. A nice saving (~34%) over the regular $11.99/month rate.
Of course the discount on iTunes cards is par for the course, with most good Ozbargainers knowing this is the regular 'everyday' price at Officeworks!
Edit: Also 20% off iTunes cards at Woolworths this week, but Apple Music cards are not explicitly mentioned, so unsure if included…
Same deal in Woolworths as well. Just went there yesterday and got the 20% off iTunes gift card.
