CostWiki
From Fabricatorz Wiki
There is no good index of costs on the ground internationally. The cost of a coffee cup at starbucks is not comparable in multiple locations. The price of beans is not so easily compared in different cities.
CostWiki is a way to say with natural language: I bought a coffee for $2.41 at Starbucks in TeeMall in Guangzhou, China.
This information is then added to a database and used to calculate costs globally on a map for comparing products amongst friends, as a research tool, and as a tool for discovering new locations when traveling.
