I've been waiting a couple of weeks for the highly OzBargain rated TCL C845 to drop price. And with the 15% discount with soundbar purchase brings the total for the 65" and cheapest sound bar to $1737.40. (currently at $1,895)
Noting appliances online are selling the 65" for $1,695.
(This deal from JBHIFI has been at 20% earlier in the year but still good)
And if you jumped on the 15% ultimate gift cards its a win win, also noting that you have to put the gift cards into your Google wallet and pay in store.
Some people have also successfully returned the sound bar for even more saving.
I would just wait for Black Friday, nothing really stands out in this deal.
