Got an email saying MySony website is on sale at the moment.
Browsing around I see this great bluetooth deal (blue only). Posted last year as well so the price is holding well. https://www.ozbargain.com.au/node/223275
I think people have mentioned before it's a good alternative to plantronics Backbeat Go 2. I'll give it a go and compare.
I'm sure there are other good deals in Sony store.
Thanks Mashimus :
Don't forget cashrewards.
Also, you should be able to use Amex ClickFrenzy (Spend $60 get $30 statement credit)
