Whenever I see a page selling anything and it won't tell me the price and I can't find it in a click, I move on. My time is valuable, and someone who plays games to waste it is not someone from whom I want to buy anything.
I used to think like that, and it used to piss me off, until I learned about market segmentation.
If SIAI approaches me to buy $WIDGET and Google approaches me to buy the same $WIDGET, I'm charging Google an order of magnitude more than I'm charging you.
