It takes a lot of effort to build a brand, I would buy a Supermarket own label probably, which also has had money invested in them.
I can see that people associate with something and keep buying that because of that, take Branston, it was not only a brand but do not remember much alternative now there is and a price issue.
Of course this is a game which can never be won as given time any association can and probably will be branded to have negative associations. So an era for non brands, quality and price. Soap Operas were called that for a reason, not sure those sort of products still advertise on the TV.
Robertson's moved away, they did not make a fuss about it, Bud went the other way effectively they put a Gollywog on the can.
