Similar to the deal in https://www.ozbargain.com.au/node/402962 however Google One has fully rolled out now for Australia.
For the price of $2.49, you can redeem $7.00 Play Store credit as your first Google One benefit which I believe can be used towards continuing the subscription too, which means 4-months for the price of $3.00 out of pocket. Alternatively you can just spend the $7.00 towards IAPs / paid apps.
- Upgrade to the 100GB $2.50 tier
- Redeem $7.00 Play Store benefit
- Cancel subscription (you still maintain benefits until 30 days has elapsed) or keep it if you want!
Go here to cancel (Cheers No!)
- Valid for one $7.00 AUD Google Play credit. Limit 1 redemption per Google One plan. Open to participants who receive a promotional code from Google One. Not reloadable; no cash value. Offer ends 2/28/19 and must be added to a Google Payments account by 2/28/19. Once added, credit must be used on Google Play by 5/31/19. Certain subscriptions excluded. Valid in Australia only.
