My mother used to say she would not buy anything that was advertised.
This is some 20 years ago when there was less ads on TV!
I think i have inherited that gene (yet to be discovered which one it is!) as I think the same.
The ads annoy me so much that I often think I will not use or buy that product -apart from the AAMI ad with Katut which I used to love.
Pleased that they stopped the ad however before we got sick of it.
No, i do not trust tv advertising as it annoys me so much!
