You know I had to make the joke, right?
Tangerine Telecom currently has a special on this NBN 100 deal where it will only cost you $69.90 a month for the first six months. It's also a no-contract plan that comes with a '14-day risk free trial'.
This deal actually makes this the cheapest NBN 100 plan on the market at the time of writing, so it's definitely worth considering.
While the price jumps to $79.90 per month after the initial six months, that's still on par with most NBN 100 plan pricing. Plus, being a non-contract plan you can always bail if you want to shop around again.
