My first time posting on this site!
This is actually a combination of two previously posted deals: found here and here
Basically, go to Coles and buy a Dick Smith gift card with 10% extra value, then use this gift card to buy iTunes gift cards from Dick Smith at 20% off. This is useful particularly if you're after cheap credit for Apple Music/subscriptions/iTunes purchases. However, because both Dick Smith and iTunes gift cards come in set denominations, the actual discount you get may vary.
Example 1:
1. Use $200 to purchase $220 worth of Dick Smith gift cards
2. Use the Dick Smith gift cards (which would pay for $275 worth of iTunes credit) to buy 2x $100, 1x $50 and 1x$30 iTunes cards. This leaves $4 to pay out of pocket.
Total cost: $204, for $280 worth of iTunes gift cards. (True Discount 27.1%).
Example 2:
1. Use $50 to purchase $55 worth of Dick Smith gift cards
2. Use the Dick Smith gift cards (which would pay for $68.75 worth of iTunes credit) to buy 1x $50 and 1x$30 iTunes cards. This leaves $9 to pay out of pocket.
Total cost: $59, for $80 worth of iTunes gift cards. (True Discount 26.3%).
Note: Dick Smith is not discounting $20 iTunes cards, so this deal only applies to $30, $50 and $100 iTunes cards.
Combine with 5% off transactions under $100 using MeBank, Citibank or ING Debit cards Paywave when buying the Dick Smith gift cards from Coles to bring the total discount to more than 30% off!
Or use Woolworths for 20% iTunes card as per comment by pket
