Some consumers perceive the quality of a product through price prior
to purchase.   This is especially so for products of higher end
quality and products of lower end quality with frequent purchase.  
Good industries in this category will include pharmaceutical and
software.   What I need is information on where I can get articles
(dowload and NOT from academic journals) that specifically talk about
some products newly launched and priced so as to enable a higher
perceived quality level.   Microsoft XP and Viagra are a good start
but I need articles from say some magazines (with pictures better
still) that I can download onine for FREE.  Answer to include specific URL.
