The problem with this logic is that although I see all these Coke, etc., ads, is that (a) I rarely drink soda, and (b) when I do it's almost always the cheap store brand. The same goes for most grocery items that aren't produce or meat. I almost never buy the branded products unless I know it's better. e.g., Cascade dishwasher detergent is noticeably superior to the store brand.
