CTREAT20
I was looking for a sound bar under $200 and managed to find this on Dick Smith eBay page. It's on clearance now so it's $179 without the voucher and Dick's old price was $249. So you're already saving $70 plus $35.80 with the 20% off code. $14.95 shipping may kill the deal for some people, but plenty of stock left around Victorian stores for free click and collect.
The cheapest deal I could found on OzBargain was a deal by Harvey Norman, $149 in June
- 2.5% cashback at Cashrewards
Out of 407 customer reviews on Amazon, it scored 4.5 stars out of 5

Save $30 with code GET30, so using ebay it's $5.80 cheaper, plus Cash Rewards, but also given that CTREAT20 has limited uses (I think once per account or something), the option is there.
