Thank you for your feedback. Yes, the main idea is that price reviews a "bound" to physical locations so of course it doesn't make sense if the good are sold online. And very good catch about the "Best deals" option (although the term "best" might have a different meaning to different people).
I believe that this service will be extremely helpful for people who are travelling. Imagine a situation: you come to a new country, you don't really know that's the average bill in restaurant in the city center, how much the tour guide to that castle costs, etc. This kind of information might be hard to find online (actually, this is when I come up with the idea - when I was planning a trip to Czech Republic and simply couldn't figure out how much money do I need to take with me). You just fire up "PriceFlurry" app and get the _sense_ (that's important, reviews are recommendations rather than something you can trust 99%) of how much the staff costs.
Again, thanks for your comments.
