RRP for the phone is $1479. If you wanted to sell it on eBay you may still get over $1400 and combined with a $1 weekend selling promo you would bank around $1350 making this plan $50 a month.
Optus is also offering free mobile streaming for 24 months on;
Optus Sport (free subscription)
National Geographic (free subscription)
Music Streaming (google play, iHeart Radio, Spotify)

**Make sure you choose the option to OWN THE PHONE as leasing is the same price.
If you sold the phone for $1300 (around $1250 after fees/postage) then it is $54 a month
If you sold the phone for $1200 (around $1150 after fees/postage) then it is $58 a month
Highly doubt anyone will pay $1400 for it from a private ebay seller rather than one from stores for $79 more.
