Sure, but why? I'm sure they love the search traffic that Google gives them. I'm not so sure they love someone scraping an internal in-store pick up API to analyze their inventory and cause incidents of "What do you mean you don't have the 64 GB Gold iPhone 5S for Verizon!? This website says you have it in stock!"
Apparently you're trying to cut down a tree in the forest with a red herring.
Google doesn't do what apple-tracker.com was doing.
Aside this thread, I'm not familiar with apple-tracker.com, however 'Froogle' (Google's shopping part of it's search engine) does do product searches, availability and price matching.
