If your older phone is need of some new protection, Telstra Plus has a variety of cases for 1000pts each. This seems to be one of the best value ways to spend your hard earned points since some of them still retail for $50+. Telstra have done promos like these before, but they were limited to the silicone cases for the Samsung S20 line only. This time both iPhones and Samsungs are included.

Apparently, free delivery on accessories until midnight tonight (though presumably this is only applicable to those who aren't gold). While stocks last. Happy hunting!
