Probably more than I think, less than they think. For higher ticket items like appliances and cars and electronics, I will be inclined to notice a product for which I have seen attractive advertising, but I will check Consumer Reports and other reviews, and talk to people whose opinions I respect before plunking down my cash. For smaller things, food, household products (cleaners and such) not at all. I am cheap, (well,“fiscally prudent” sounds a little nicer) so I read the labels and tend to buy generic. I do enjoy well-crafted advertising, however, I find a lot of it to be very creative and interesting. Extra points for making me laugh out loud.
