Just saw this ad in the SMH
Buy a Z10 (outright or on plan) and then claim $100 cash back, and also trade in your old phone.
They have the trade in prices on the bouncemobile.com.au website - of course conditions apply (working condition phone blah blah blah)
So maybe find the cheapest one - last deal was $399 from wireless1 but thats finished
Deal started 18 July so anyone whole bought one from then can claim
Includes phone being bought on a plan!
just fyi. found in the extra fine print in the T&C's
To be eligible for the Blackberry Trade-in Program you must:
"have purchased a new BlackBerry Z10 STL-100-2 between 18 July 2013 and 31 August 2013 from either a Telstra, Optus, Vodafone, Harvey Norman, JB HiFi or Fonezone store (including their online stores) in Australia (a "New BlackBerry Z10")"
not sure if it will apply to other retailers?
