Samsung Galaxy A30 (Black) Optus prepaid phone $269 at Target.
$259 if you sign up to the Target enewsletter first (see note below).
Free delivery, or free click and collect.
Might suit someone already on an Optus Prepaid plan.
Free Optus network unlock after recharging at least $80 (or $25 after 6 months if recharged less than $80).
Note: If you sign up to the Target enewsletter https://www.target.com.au/enews/quick before you order the phone, you will get a unique code for $10 off one online purchase over $50.
You can then use the code to buy the phone for $259.
If the link to the enewsletter signup doesn't work, you can usually find one on the deal page itself.
It's $299.00 on the website now, perhaps you can get it to $289.00 by using the code.
You can still get it for $272.00 from tobysdeals, here:

but thats a grey import so warranty will be a pain and possibly 4G bands may not match
