Received an email from Flybuys:
Optus 100/20Mbps NBN for $79 for the first 6 months (normally $99/month - $120 saving over 6 months). plus collect 30,000 points(worth $150 Flybuys Dollars) when you stay connected for 3 months.
Month-to-month plan. $0 start-up fee. Unlimited data.
After accounting for $150 Flybuys dollars, the plan cost is $29/month over 3 months. Don't forget to sign up using Shopback or topcashback for additional cashback.
Yeah, I'm basing it off the invoice date which is the same as anniversary date for the connection. I am hoping to give them notice on 17th June so I'm covered for 30 days before the next invoice drops.
