That is in fact,a classic example of "biting the hand that feeds them".
I'm sure Super Amart,the Good Guys,RetraVision,Bunnings,etc.would be unimpressed,by effectively being told that they sell overpriced crap!
Commercial TY Stations do have some commitment to their paid advertisers & program sponsors,but these are pretty well balanced by the fact that competitors all advertise.
So far,the balance of power has been in the TV Network's favour,so upsetting,say Coles,is unlikely to lead to removal of advertising in Prime time.
This allows the Networks to cover other cheaper suppliers,& make themselves look like "the battler's friend"
I always take these stories of "bargains" with a grain of salt,as there are always "ifs" & "buts" when you come to accessing them.
They made a big fuss about Kogan at one time,but I've never seen any paid advertising for them.
I have heard reports elsewhere about poor service from that company.
