There's a mention about selecting a "shoe lover profile" when shoe shopping or something along those lines so it seemed to me that this was accounted for.
"For instance, if a user decides to go shoe-shopping for summer, he or she could equip their browser with the cookies most associated and aligned with shopping, shoes and summer"
You could do the same thing by trial and error switching profiles or some kind of way of sharing "this profile gives low prices at X travel site" information between users.
That wouldn't affect differentiated pricing based on user profile information. It would get you more ads in that vertical but wouldn't get you the cheapest prices.

The shoe shopper could also just go to http://www.google.com/ads/preferences/ and add it under the "Interests" section.
